your mom 

Commonly used by prepubescent teenagers, this "comeback" is used to suggest that the person in whom this is directed to has clearly verbally beat the shit out of them. Often this phrase will come before crying and lying in the fetal position.

Verbal Abuser: You're a cock smoking twat who enjoys his uncles company on his birthday in the games closet.

Verbal Abusee: *Sniffles* Your Mom!
