An outrageously gangsta expression a person will make when he doesn't give a fuck and is truely balling like a motherfucker, typically accompanied by middle fingers and rockstar signs. The statement is not to be taking literally; it is simply a fun expression without any expectation of response. However, fucking and balling are always fun.

Joe: "yoooooo!"

random dude: "haha you're drunk as fuck man!"

Joe: "Fuck you! I'm ballin!"
