OPP slang means opponent or opposition. People use it to describe a rival, an enemy, or anyone on the other side of a conflict. It is usually written “opp,” and the plural is “opps.”
You may have seen it in a rap lyric, a TikTok caption, or a group chat and wondered if the person was serious. Sometimes they are. Often they are joking. The tone, the platform, and the speaker change the meaning.
This guide explains where OPP slang came from, how Gen Z uses it, what it means in medical settings, and how to reply when someone calls you an opp.
Defining the Core Meaning of OPP
OPP is slang for opponent or opposition, meaning a person or group that works against you. It can point to a rival, a competitor, or someone you simply dislike.
The word grew out of African American Vernacular English and hip hop culture. It is short for “opposition.” Today it also shows up in social media posts, memes, and everyday chats.
People use it in three main ways:
- As a noun: “He is my opp.”
- As a plural: “Watch out for the opps.”
- As a verb, less common: “They tried to opp me.”
The Historical Evolution of the Term
The letters OPP first reached mainstream culture in 1991, when Naughty by Nature released the song “O.P.P.” In that song, the letters stood for “Other People’s Property,” a phrase about being involved with someone else’s partner.
The modern slang followed a different path:
- Early 2010s: Drill rap rose in Chicago. Its lyrics are often adversarial, and rival artists were called “opps.”
- From 2012: UK drill started in Brixton, London, and “opp block” became common in London too.
- By 2020: Twitter and TikTok turned “opp” into everyday Gen Z vocabulary.
Some slang guides say the 1991 song helped spread the letters. Others say the new meaning comes straight from “opposition.” Either way, today’s meaning is about rivals, not romance.
OPP Meaning in Text

In text messages, OPP almost always means opponent or enemy. The writer is calling someone a rival or a person they do not trust.
Here are some typical chat examples:
- “Don’t tell her our plans, she’s an opp.” (a rival)
- “My little brother is my biggest opp lol.” (a joke)
- “That’s opp behavior.” (acting against you)
Look for signals like “lol,” emojis, and exclamation marks. They usually mean a joke. A flat, short message with no humor can signal real tension.
What is OPP Slang For?
OPP slang is used to label someone on the other side of a contest, conflict, or disagreement. One short word replaces a long explanation.
People use it for:
- A rival rapper or crew in hip hop and drill
- A competitor in sports or gaming
- Someone who hates on you or dislikes you online
- A small annoyance, said as a joke
The meaning is flexible. The seriousness depends on the speaker.
What Does OPP Mean in Gen Z?

For Gen Z, OPP means a rival or someone who is against you, and it is often said as a joke. Generation Z covers people born from about 1997 to 2012, according to Wikipedia.
A TikTok teacher known as Mr. Lindsay told TODAY.com that kids often use “OPP” in a light way. They may say it when an adult expects chores or schoolwork. He sees it as a compliment when it comes from holding students accountable.
Titania Jordan, the chief marketing officer at Bark.us, says parents should still stay involved in how kids use slang.
Usage Across Different Social Contexts
The meaning of opp changes with the setting. This table shows the most common cases.

OPP Meaning in Medical

In medicine, OPP stands for organophosphate poisoning. Organophosphates are chemicals used mainly as insecticides. They are also found in some medications and nerve agents.
Symptoms include extra saliva and tears, small pupils, muscle tremors, and confusion. Exposure can be accidental or deliberate. Doctors treat it with medicines such as atropine.
The World Health Organization estimates about 200,000 deaths each year from this poisoning, mostly in the Asia Pacific region. Anyone who suspects exposure should call emergency services right away.
Veterinary science also uses OPP for ovine progressive pneumonia, a chronic infection in sheep.
Addressing Common Misconceptions
Many people misread OPP because the same three letters carry several meanings. Here are the biggest mix ups:
- Myth: Opp always means violence. Fact: Many people use it as a joke, especially online.
- Myth: OPP still means “Other People’s Property.” Fact: That was the 1991 song. Modern slang means opponent.
- Myth: OPP and OP are the same. Fact: OP usually means “original poster” or “overpowered.”
- Myth: Only enemies are opps. Fact: A friendly competitor can be an opp too.

Regional and Cultural Variations
Opp is most common in the United States and the United Kingdom, while OPP means something else in Canada. In Canada, OPP is the Ontario Provincial Police, which patrols provincial highways and investigates complex crimes.
Other regions add their own flavor:
- Chicago: Home of early drill rap, where “opps” meant rival artists and crews.
- London: UK drill uses “opp block” for a rival’s area. One guide points to Brixton versus Peckham as an example.
- New York: Brooklyn drill grew from Chicago and UK drill, so the slang travels with the music.
The word comes from Black American communities and hip hop. People outside those communities should use it with care, because overdoing it can sound like mockery.
Usage in Dating Apps and Online Communities
On dating apps, an opp is a romantic rival, an ex, or someone from a rival friend group. A typical line is, “She is talking to the opp.”
In online communities like Discord servers, Reddit threads, and gaming lobbies, opp usually means a competitor or someone on the other side of a debate. Do not confuse it with “OP” on Reddit, which means the original poster.
On a first chat, calling someone’s ex an opp reads as negative. Keep it light.
Addressing Potential Offense and Professionalism
Calling someone an opp can offend because the word literally means enemy. Even a joke can land badly with people who do not know you well.
Follow these rules:
- Avoid it in emails, job chats, and client messages.
- Write out “opportunity” in business messages, since “opp” can confuse readers.
- Do not label real people as opps in public posts. It can look like harassment.
- Check the audience first. Friends may laugh. A boss may not.
