*see suck monkeyhole
Came into use when a girl got tired of your mom, your face, and monkeybone come backs.
girl: Suck monkeyhole!
(It's technically impossible to suck a monkey's asshole, so don't actually attempt it. The phrase "suck monkeyhole" is said to someone that is so full of shit, that they should go suck the shit out of a monkey's asshole to keep a steady supply.)
