Used to initiate conversation with your close friends. Usually followed by "BITCH" or something of the likes, it is a very useable phrase.
BOB: Sup, yo? Bitch? Wat up nigga?
FRED: Call me Bitch again and i'll break ur face!

orignated from the acronym SYDM (shut your damn mouth) but has become the nonsensical phrase for "what's happening/going on?"

Get the sup yo dog money mug.
A common greeting between two niggers

However if a white person uses the exact same
phrase when greeting a nigger, they are highly
offended.

1st. Nigger: Yo Sup Nigga?

2nd. Nigger: Hey Bro, Sup wit you nigga?
