Mattress Monster

A Mattress Monster is a fat and or butt ugly broad who likes rough and dirty sex and is likely to be infected with multiple varieties of crotch rot.

Dude 1: "Hey man, that broad's hot. I'd do her so hard her grandmother would cum!"
Dude 2: "Oh man! That's sick, you couldn't pay me to stick my dick in that fucking mattress monster. She looks like the love child of Roseanne Barr and Caitlyn Jenner!
