This is used to describe someone called Oliver who is a fat shit who should jump of a cliff because of their lifestyle of eating. He does nothing but eat he will never unfortunately have sex because he is so fat he will just belly bounce the lady and he has a shrivelled penis.

Get the Fat shitmug. "The Fat Shit" is a well used nickname towards a special type of human being which enjoys having his daddies throbbing cock rammed inside him until he splurges his thick white semen into his rectum. He is very well known for being a faggot a couple years back, and is really shit at the popular videogame "Brawlhalla." He also love ripping one out to NeoVR's sister, who was already used up by Colby Coe. Not only does "The Fat Shit" loves it when his dad nuts in his butt, but he loves it when he swallows his brothers fresh from daddies huge purple nutsack
Person 1 "The Fat Shit nigga jerked off to NeoVR's sister, and then licked up his own cum!"
Person 2 "BRO WTF, I heard his dad cums deep in his mouth and makes him swallow it!"
