Just because you got good head, I'mma break bread
So you can be livin it up?

from Linkin Park (Ft. Jay Z) – Big Pimpin'/Papercut Lyrics on Rap Genius

Meaning

Jay is not going to marry a girl just because she has “good head” (give good blow jobs)

To “break bread” usually means to build a relationship; here, Jay is using it sarcastically to mean breaking his “bread” (slang for money) in half if he gets a divorce
