mc streetwise

Chicago slang for somebody who's acting like his connections are the largest of the hood and he's the most powerful man inside the web, as he's not. In fact, he's a selfish, lazy fuck who spends most of the time on his own.

You didn't mean like going out with your neighbour?
-Why not?
Honey, didn't I just fuckin' tell ya that this guy's mc streetwise like fuckin' hell. Dump il fuckin' bastardo!
