But now my balls, balls deep in this broad's jaw
Swallow girl, it's just nut
Tyler creates the picture of girl giving him some oral pleasure. Note the use of wordplay on balls, balls deep. Furthermore, he uses a homophone on nut', giving it two meanings:
Nut' as in, the ejaculation of his load into her mouth.
Nut' as in, the act of doing that is just “nothing”. He implies that her doing that is expected and not as big of a deal she may think it is.
