Reddit Slang and Terms Every Marketer Needs to Know

Post on Reddit using terms you learned from a marketing blog and the platform will smell it in seconds. Reddit runs on its own vocabulary, and getting it wrong (calling a moderator an "admin," asking "what's your karma score" in the wrong tone, missing what OP means) marks you as an outsider before anyone reads a word you wrote. This is a working reddit slang glossary: the account and karma terms, the moderation terms, the culture terms, and the marketing-specific terms (astroturfing, brigading, sockpuppets, the 9:1 rule) that separate brands who understand the platform from brands who get banned on it.

Bookmark it. Reddit's language shifts slowly but it shifts, and half the value of a glossary like this is not getting caught using last year's version of a word.

Reddit slang: karma and account terms

These describe how Reddit tracks a user's standing and activity. Karma is the first thing any Redditor checks on a profile, and marketers need to understand what it actually measures (not much, functionally, but a lot socially).

Karma - A numeric score tied to a user's account, built from upvotes minus downvotes on their posts and comments. Reddit splits it into post karma (from submissions) and comment karma (from replies). It opens up posting privileges in some subreddits and signals account age/legitimacy, but it is not currency and has no functional power on the platform itself.

OP - Short for "original poster," the person who created the thread you're reading. In comment threads, "OP" refers back to that person specifically, not just anyone in the conversation.

Cake day - The anniversary of the date an account was created. Reddit shows a small cake icon next to a username on their cake day, and it's a minor community tradition to acknowledge it.

Lurker - Someone who reads Reddit regularly but rarely or never posts or comments. The vast majority of Reddit's traffic is lurkers; the visible posting/commenting population is a small fraction of total readers.

Throwaway (account) - A secondary, often anonymous account created for one specific post or conversation, usually to avoid tying sensitive content to a main identity. Common in advice or confession-style subreddits.

Karma whore - A derogatory term for someone who chases karma for its own sake, often by reposting popular content or writing bait comments, rather than contributing anything original.

Karma farming - The practice of artificially building up karma fast, sometimes through reposting proven content, sometimes through coordinated or automated upvoting. It's against Reddit's spirit even when it doesn't technically break site rules, and accounts that farm karma too aggressively get flagged by both users and Reddit's own systems.

Shadowban - A site-wide restriction where a user's posts and comments become invisible to everyone except themselves, with no notification that it happened. Reddit uses it against accounts that look like spam or bot activity. A shadowbanned brand account will keep posting into a void and never know why engagement went to zero.

Moderation and rules terms

Every subreddit is run by volunteer moderators with their own rules layered on top of Reddit's site-wide policies. Knowing this vocabulary matters because moderators are the actual gatekeepers of whether your content survives.

Mod (moderator) - A volunteer user with expanded permissions in a specific subreddit: removing posts, banning users, editing community rules, pinning threads. Mods are not Reddit employees. Each subreddit has its own team and its own tolerance for promotional content.

Admin - A Reddit employee with platform-wide authority, distinct from a subreddit moderator. Admins handle sitewide policy violations (harassment, illegal content, coordinated manipulation); mods handle their own community's rules.

Rule 1 / sub rules - Subreddit-specific posting guidelines, usually pinned in the sidebar or a wiki page. They vary enormously between communities and are enforced independently of Reddit's site-wide content policy. Ignoring a subreddit's stated rules is the single fastest way to get a post removed or an account banned.

Removed / [removed] - A post or comment taken down by a moderator, shown as "[removed]" where the content used to be. Different from [deleted], which means the user removed it themselves.

AutoModerator (AutoMod) - A bot most subreddits use to automatically filter, flag, or remove content that matches certain rules (link spam, banned keywords, new-account posting). A lot of "why did my post disappear instantly" moments are AutoMod, not a human mod.

Flair - A tag attached to a post or username within a subreddit, used to categorize content (e.g., "Discussion," "Question," "Success Story") or denote a user's role or expertise. Many subreddits require flair before a post is even visible.

Community and culture terms

These are the everyday vocabulary of how Reddit talks about itself, and using them naturally (or badly) is an instant tell for whether an account is a real participant or a brand wearing a costume.

Subreddit (sub, r/) - A community dedicated to a specific topic, always prefixed with "r/" (e.g., r/SaaS, r/startups). Reddit is really thousands of separate communities with their own norms, not one homogenous audience.

AMA - "Ask Me Anything," a format where someone (often verified with proof) opens themselves up to unrestricted questions from the community in a live thread. High-effort AMAs from founders can build real credibility; low-effort ones read as a stunt.

Crosspost (x-post) - Sharing a post that already exists in one subreddit into another subreddit, with attribution to the original. It's a native Reddit feature, not manual copy-pasting.

NSFW - "Not Safe For Work," a tag applied to content that's explicit, graphic, or otherwise inappropriate for a work or public setting.

TIL - "Today I Learned," both a specific subreddit (r/todayilearned) and a general phrase used to introduce a fact someone recently discovered.

ELI5 - "Explain Like I'm 5," a request (and subreddit) for simplified, jargon-free explanations of complex topics.

TL;DR - "Too long; didn't read." A short summary placed at the top or bottom of a long post so readers can get the gist without reading everything. Expected practice for any post over a few paragraphs.

Wall of text - A dense, unformatted block of writing with no paragraph breaks, line spacing, or structure. Considered bad form on Reddit and often ignored regardless of content quality, because the platform's readers expect scannable formatting.

Repost - Content that has already been posted before, often flagged by other users (sometimes with bots that detect and link the original). Frequent reposting without adding anything new damages an account's credibility.

Hivemind - A semi-critical term for the way opinion on Reddit (or within a specific subreddit) can converge quickly and uniformly, with dissenting views getting downvoted into invisibility rather than debated.

Downvote brigade / pile-on - Informal terms for a large number of users quickly downvoting the same post or comment, often in response to something perceived as promotional, tone-deaf, or rule-breaking. Not the same as brigading in the formal sense below, but the visible symptom of it.

Marketing-specific terms brands need to know

This is the section that actually matters if you're a brand trying to operate on Reddit responsibly. Some of these describe tactics Reddit explicitly bans. Understand them not because you should use them, but because knowing what they are is the only way to avoid accidentally doing something that looks like them.

Astroturfing - Creating the appearance of organic, grassroots support for a brand, product, or opinion when it's actually orchestrated by the brand itself, usually through fake or paid accounts posing as ordinary users. It's against Reddit's content policy and it's also just bad strategy: Redditors are unusually good at spotting inauthentic enthusiasm, and getting caught astroturfing tends to do more damage than never posting at all.

Brigading - Coordinated action by a group of users, often organized from one subreddit or an outside platform, to vote-manipulate or harass another subreddit's members or content. Reddit treats brigading as a sitewide policy violation, not just a subreddit-level issue.

Vote manipulation - Any coordinated or artificial attempt to inflate or suppress votes on a post or comment, whether through fake accounts, vote-trading arrangements, or asking outside audiences to go upvote something. Reddit's content policy prohibits this outright, and it's detectable through voting pattern analysis on Reddit's end.

**Sockpuppet** - A fake account, or a secondary account operated by the same person, used to impersonate an independent voice. Brands sometimes use sockpuppets to praise their own product or attack a competitor while appearing to be an unrelated third party. It is against Reddit's rules and it is exactly the kind of thing an experienced Redditor can usually smell within a few comments.

Shill - An account (real or fake) that promotes a product, service, or opinion while pretending to have no connection to it. "Shill" is also one of the most commonly thrown accusations on Reddit, sometimes fairly and sometimes not, which is part of why unmarked self-promotion is risky even when it's technically honest.

Self-promo (self-promotion) - Any post or comment where the poster is promoting their own product, content, or business. Most subreddits either restrict self-promotion to specific days/threads or ban it outright. Reddit's own site-wide guidance is the 9:1 rule (below), and individual subreddits often layer stricter versions on top.

The 9:1 rule - An informal but widely cited guideline: for roughly every nine genuine, non-promotional contributions a user makes (comments, helpful answers, unrelated posts), at most one can be self-promotional. It's not an official Reddit policy with an enforced ratio, but it reflects how the platform's culture and most moderators actually judge whether an account is a real participant or a brand extracting value. Accounts that skew promotional past that ratio get flagged, downvoted, or banned regardless of how good the product is.

Bot account - An automated account, sometimes disclosed (many subreddits run helpful utility bots) and sometimes not. Undisclosed bots used for promotional purposes are a policy violation and one of the fastest ways to get an entire domain banned from Reddit, not just one account.

Native content - Content written specifically for Reddit's format and a specific subreddit's norms, as opposed to content repurposed from a blog, ad, or press release and dropped in unchanged. Native content is a soft requirement, not a formal rule, but posts that read like marketing copy get buried by the vote system regardless of what any single moderator does.

FAQ

What does OP mean on Reddit?

OP stands for "original poster," referring to the person who created the thread being discussed. It's also sometimes used loosely to mean "original post," as in "did you read OP's edit?"

What's the difference between karma and awards?

Karma is a cumulative score built from upvotes and downvotes across all of a user's posts and comments over time. Awards are a separate, optional feature where users spend Reddit's virtual currency (or real money) to give a specific post or comment a visible badge, sometimes with a small karma bonus attached. Karma reflects overall standing; awards are a one-time signal on a single piece of content.

Is astroturfing the same as brigading?

No. Astroturfing is faking grassroots support for something (usually a brand or product) by posing as unaffiliated users. Brigading is coordinating a group to vote-manipulate or harass a different community. Both are against Reddit's rules and both get accounts and domains banned, but they describe different behaviors: one fakes authenticity, the other coordinates an attack.

Speaking the language is step one

None of this is complicated once you've seen it laid out, but knowing the vocabulary only gets a brand to the starting line. The actual work is showing up in the right subreddits consistently, contributing before promoting, understanding each community's specific culture on top of Reddit's general one, and building a presence that survives contact with a platform that punishes anything that smells like astroturfing, brigading, or vote manipulation. We don't do any of that at subredditmarketing.com. No upvote hacks, no karma buying, no sockpuppets. Just the account work and content strategy that gets funded SaaS, fintech, and DTC brands treated like real community members instead of advertisers.
