A crime committed against all that is good and holy by a woman when she kisses a man and has performed oral sex on another man within 24 hours. The man is then infected with Cockmouth, from which he can readily discern the taste of cock or ballsack, and in the most severe scenarios can taste the "taintsalt."
"I think that girl at the party gave me cockmouth."
"I'm a horrible soulless bitch and blew this guy in the gas-station bathroom before making out with my boyfriend."
"That chick just blew me, and now she's giving her boyfriend Cockmouth!"
the strange aftertaste in your mouth after having snorted a few lines of coke. Taste is a little bitter(not too bad) and leaves your mouth a little numb.
