A corruption of "What is up, my brother?." Since it's annoying to say "wassup" after Budweiser co-opted it for an advertising gig, we now say sup. It even works IRL.
Sup is actually a rhetorical question as nobody really cares about anything that is actually up. Plz, don't use a question mark with it or otherwise people will give you their life story.
If you must answer a "sup", the only correct answers are "nm" or "nmu."
For camwhores, "Sup" is the correct method of addressing a *chan, most commonly on /b/ by writing said words on a body part or object. The appropriate response is to request for them to kindly display their mammaries at once or hastily excuse themselves from the board.
