And I don't even need a G pass, I'm past that
I'm passing 'em out now and you can't have that
A G pass is a “gangster pass” which is like a certificate of authenticity of gangsterness. Wayne is now sufficiently gangster that people know it even if he doesn’t have the pass: in fact, he’s now in charge of doling them out (that’s a hard job to get!)
Also, if you tip a stripper a lot of money, it could be described as “trying to buy a G pass” (i.e., trying to give her $1,000 in tips so that she’ll let you touch her special parts)
It’s likely that Weezy intends this as a 2nd meaning, since he flashes a wad of dollar bills in the video when he says it
