"If I ain't on some shit, I'm gettin' on it."
Jadakiss, Kiss Of Death
This isn't something and doesn't really mean anything. I get the sense that Jadakiss is the kind of guy that you just nod your head at and say "Oh, that's pretty cool." It's also kind of weird that he doesn't know if he's on shit or gettin' on it... Whatever "shit" may be.
