What Does “sup” Mean in Chat?
At its core, “sup” is shorthand for “what’s up.” It’s a casual greeting used widely in texting and online conversation. You can think of it as equivalent to “hey,” “hi,” or “how are you.”
- Sup = What’s up
- Literally, it asks “What’s happening?” or “How are things?”
Example Chat Use:

Is “sup” a Full Form, Abbreviation, or Slang?
This is where things get interesting. Strictly speaking:
- “Sup” is not a formal full form.
- It’s an abbreviation, a piece of internet slang that evolved from spoken language.
People treat it like a word because it’s short and widely understood, but it didn’t originate as a “dictionary term.”
So when users search sup full form in chat, they are really looking for:
- The expanded idea behind sup (i.e., what’s up)
- The meaning in different chat contexts
- Whether it’s correct in professional settings
The full form answer often given is “What’s up?” but in formal writing, you should avoid using sup.

Unless you’re writing to someone you know well in a casual context, sup is too informal.

Depending on tone and context, it can function simply as “hello” without literally asking a question.
