"Sup" is a shortened version of "what's up," a common greeting in British slang. It's a casual way to say hello and ask how someone is doing.
Here are some ways "sup" is used in British slang:
- As a greeting: "Sup, mate! How's it going?"
- To express surprise: "Sup! Didn't expect to see you here."
- To show interest or excitement: "Sup with the new car, then?"
"Sup" is generally considered informal and is often used among friends and peers. It's not typically used in formal settings or when speaking to someone you don't know well.
