I would imagine that, if a girl were to grab a guy flying in the air by his balls, it would put him out of the game (can’t really be a playa with no balls)

wait/weight wordplay

This line sets up the theme of towering over everybody else in the game (both figuratively and literally)

Bars as in lyrics, and well as bench pressing (lifting weights on a bar in the air, commonly done in a gym)

Along with talking tough, there’s some scatological wordplay (shit/behind)

Shakin my motherfuckin' head, an alternative to the facepalm

Continuing the religious theme, Chop does a bit of wordplay with “missionary”.

A “missionary” is somebody who preaches to the masses, be it religious or else. Chop’s “missionary flow” preaches the truth and washes away the bullshit of other rappers. He ends it with “coming off top”, meaning that he’s got everybody in the game beat.

However, “missionary” is also a sexual position, in which the guy is on top of the girl. When you pull out (it’s 99.99%* guaranteed to work!) you would cum (come) on top of her.

“Based God” is a nickname for “rapper” Lil' B.

By replacing God with Chop, Chop declares himself an almighty deity.

Head, fellatio, etc.
