look up any word, like ethered:
when a female is performing fellatio, and after she gets the complete schlong into her mouth, she "goes for the gristle" by getting one or more testicles into her mouth.

This came from trying to get the extra meat on the gristle on the chicken bone when you are done eating wings and are still hungry.
Dude 1: You bang that girl last night?
Dude 2: Nah, but she went down on me
Dude 1: She go for the Gristle?
Dude 2: Hellz yea! Gave her a mouthful! BOTH BALLS!
