You’re a few comments deep into a Reddit thread and someone writes “OP, any update?” or “not OP but this happened to me too.” If you’re new to the platform, that’s usually the moment you go looking for a translation.
Featured Snippet Answer On Reddit, OP stands for “Original Poster” — the person who created the thread or post being discussed. It’s used throughout comment sections to refer back to that person without repeating their username, as in “OP never explained why” or “waiting on OP to respond.”
Quick Answer Table
| Term | Meaning | Common Use | Tone |
|---|---|---|---|
| OP | Original Poster | Referring to who started a thread | Neutral |
| OP | Overpowered | Gaming and gaming-adjacent subreddits | Casual, often exaggerated |
| Not OP | Not the original poster | Sharing someone else’s content | Neutral, clarifying |
What Does OP Mean on Reddit?
On Reddit, OP means “Original Poster.” It refers to whoever created the post that a comment thread is responding to. Instead of typing out or tagging someone’s username every time, commenters just write “OP” to refer back to them.
Basic Example
“OP, do you have any pictures of the damage?”
This is a commenter directly asking the person who made the post for more information.
“OP never responded, so we probably won’t get an update.”
Here OP is used the same way you’d use “they” or “the poster” — a stand-in for the person who started the discussion.
Capitalization doesn’t matter much. You’ll see OP, op, and Op used interchangeably, though uppercase is more common since it reads clearly as an acronym.
OP as “Overpowered”: The Other Common Meaning
OP has a second, unrelated meaning that shows up constantly in gaming and gaming-adjacent subreddits: “overpowered.” It describes a character, weapon, build, or strategy that’s disproportionately strong compared to everything else available.
Example
“That new sniper rifle is so OP, nobody stands a chance.”
This has nothing to do with who posted anything — it’s a comment on game balance.
How to Tell Them Apart
Context makes the distinction almost automatic. If OP is being used to refer to a person — asking them a question, thanking them, or describing what they said — it means Original Poster. If OP is describing an item, character, or ability as too strong, it means overpowered. The two meanings essentially never overlap in the same sentence, so confusion is rare once you’ve seen both used a few times.
“Not OP” and Other Related Phrases
You’ll frequently see variations built around the core term:
“Not OP”
Someone writes “not OP” when they’re sharing content that isn’t originally theirs — often a screenshot or a repost from elsewhere — to make clear they aren’t claiming credit for it.
“OP’s Post” or “In the OP”
This refers back to the original post itself, not just the person. “Like OP said in the post…” points readers to information already shared at the top of the thread.
“Update, OP Here”
When the person who started the thread comes back to add new information, they’ll often identify themselves this way so readers know the update is coming directly from the source.
Why Reddit Relies on “OP” So Heavily
Reddit threads are structured differently from most social platforms — a single post can generate thousands of nested replies, often from people who never interact with each other directly. “OP” solves a practical problem: it gives everyone a shared, neutral way to refer to the thread’s original author without needing to remember or retype a username each time. It also carries over cleanly from older internet forums, where the same shorthand served the same purpose long before Reddit existed.
Where Else You’ll See OP
While Reddit is where most people first encounter the term, it isn’t Reddit-specific. The “original poster” meaning shows up across other platforms and forums too — Twitter/X threads, Instagram comment sections, TikTok, and general online forums all use OP the same way, referring to whoever started the post or thread being discussed.
When Is It Appropriate to Use OP?
OP is standard, community-wide language across nearly all of Reddit — it’s not considered rude, overly casual, or niche slang the way some texting abbreviations are. It works in:
- Direct replies to the thread creator
- General discussion about who said what earlier in the thread
- Clarifying whether you’re sharing your own content or someone else’s
The one place it doesn’t translate well is outside forum-style discussions entirely — texting a friend “OP said…” about something from a group chat, for instance, would likely just cause confusion, since the term assumes a threaded, multi-reply structure that ordinary texting doesn’t have.
Common Misunderstandings About OP
- Mixing up “Original Poster” and “overpowered.” The subreddit and sentence structure almost always make it clear which is meant, but it can briefly confuse newcomers moving between a general-discussion subreddit and a gaming one.
- Assuming OP always refers to a Reddit account’s regular activity. OP only refers to the person’s role in that specific thread — the same user might be “OP” on one post and just another commenter on the next.
- Thinking “not OP” is a criticism. It’s simply a disclosure that the content being shared belongs to someone else, not a negative judgment.
Frequently Asked Questions

The Takeaway
On Reddit, OP almost always means “Original Poster” — a simple way to refer to whoever started the thread without repeating their username. The one exception worth remembering is gaming subreddits, where the same two letters often mean “overpowered” instead. Once you’ve seen both used a couple of times, telling them apart becomes automatic — the subreddit and sentence structure do most of the work for you.
