The act of surveiling your mate to see if they (usually a
female) have been
cheating. Literally, checking her chin for the testicles of another man to whom she has been giving oral sex. Made famous by the Snoop/Dre song, "
Bitches Ain't Shit."
"...Snoop we got news/
Your
girl was trickin' while you was draped in your county blues/
I ain't been out a second and already gotta do some muthafuckin chin checkin/
Move up the block as we groove down the block/
See my
girl's house, Dre, pass the glock/
Kick in the do', I look on the flo'/
It's my little cousin Daz and he's fuckin' my hoe, yo/
(Bitches ain't shit)
I uncocked my shit...I'm
heart-broke but I'm still loc'ed
Man, fuck a bitch!" - Snoop
Dog and Dre, "Bitches Ain't Shit"
