An insult*, usually used as a comeback when someone insults your credibility, swag, and sexual orientation. This means many things:
1. By asking him, "Who'
s yo mans?" you are implying that he is gay and has a
pimp.
2. You are calling him a bitch.
3. You are saying that he can't do shit without asking his
pimp, and that he's the bottom bitch in his homosexual relationship
.
Using the word "nigga'' at the end
will undoubtedly increase the ghetto-ness of the phrase but also imply you are not fucking around. A simple example of this is provided below.
*Can also be used jokingly around good
friends.
