Mate, did you look on facebook last night? Jane was being a total facecunt to Aida.
another word for mouth
shut your facecunt
don't talk with your facecunt full
i'm facecunt smacked
A woman's (or man bitch's) mouth.
Shut your face-cunt, men are talking.
A mouth; specifically, one optimally designed for sucking copious amounts of semen out of oversized penises. When a faggot cumdump is in his customary "full-service" position (on all fours), the facecunt is the forward-facing fuckhole, equipped with a tongue; the rear fuckhole is properly known as a "boypussy" or, in more mature specimens, as a "mancunt."
Me and my frat brothers slammed that fuckbitch's facecunt so hard and so long, he fuck near drowned in jism.
