OP = Original Poster
On forums and Reddit, OP is the person who created the post. Reddit marks that person’s comments with an OP label next to their username. [Link: Reddit Help page]
- “I agree with OP.” means “I agree with the person who made the post.”
- “OP, can you explain what happened?” means “Person who posted, please explain.”
OP can also mean the original post itself. “Read the OP before commenting” refers to the post, while “Ask OP what they meant” refers to the person. [Link: Dictionary of Social Media reference]
On TikTok or Instagram, OP can mean the original creator, but this is less standardized than Reddit’s official label.
OP = Overpowered
In gaming, OP describes a character, weapon, ability, or strategy that is stronger than the game’s balance intends. “That gun is OP” means it is too strong compared with the alternatives.
A useful clue is the word nerf, which means reducing something’s strength. “This champion is OP, please nerf it” is about power, not posting. Words like buff, broken, and meta point the same way.
OP = Opening (Anime)
In anime discussions, OP is the opening sequence or theme song. “The new OP is amazing” is about the intro, not the strongest character. The same thread can use both senses: “The OP is beautiful” (opening) and “That character is OP” (overpowered). [Link: Fanlore]
op / opp / opps = Opponent or Rival
Lowercase op, opp, and the plural opps mean an opponent, rival, or someone on the opposing side. The term comes from urban slang, especially rap and hip-hop culture, and has spread into everyday slang among younger people online. awario
- “Don’t tell my op about the plan.” (rival)
- “The opps are talking again.” (the opposing side)
- “My brother is officially my op today.” (a joke)
Tone matters. It can be playful among friends or in a gaming lobby, but in a real conflict it can carry a serious meaning. Some teens use “OPP” lightly for anyone who opposes them or causes a minor inconvenience, such as an adult expecting them to do chores. In school or work writing, use “rival” or “opponent” instead.

OPP also has a different sense: the 1991 Naughty by Nature song “O.P.P.” uses it for “Other People’s Property.” awario
Other Meanings of OP

How to Tell Which OP Someone Means
Look at what OP is attached to:
- A person who posted something: Original Poster. “OP replied to my comment.”
- Strength: Overpowered. “That character is OP.”
- An anime intro or theme: Opening. “Did you skip the OP?”
- Someone opposing you: Opponent. “He’s an op.”
- A piece of content: Original Post. “The answer is already in the OP.”
Capitalization can hint at the meaning, since lowercase “op” and “opps” often mean rivals, but it isn’t reliable. The surrounding words matter more.

Where Did OP Come From?
There is no single origin. “Original Poster” grew out of forum culture, where people needed a short label for whoever started a thread. “Overpowered” developed in gaming communities, and the opponent sense developed in hip-hop and street slang. Urban Dictionary entries from 2007 and 2010 already list both original poster and overpowered. Exact first uses are hard to pin down, so be cautious about claims that a specific person or website invented any of these meanings.
