a person who engages in sexual acts with a women of the birthing abilites. and she has used those abilities to take one in the kooch so she could plop out a psycho little fuck 9 months later. he is also damned by god, so he musta fucked alot of mothers, and they are a bitch which is a female dog or a trashy hoe. like that one chick from high school who sucked off the whole football team before every game to get them ready

A vast majority of guys in internet chat rooms, who cannot seem to grasp the basic principles or respect, class and dignity...or the concept that most women dont want to see their dicks...no matter how proud you may be of it. This also cover guys who think jacking off in front of random women is in anyway at all a turn on to us.
If one more Crayon Eating Motherfucker sends me a dick pic I am going to spray mace in his dickhole!

Fat is just rude. Rats are disgusting. So Fat Rat goes fine together, but doesn't sound right. Therefore Fat Rat motherfucker just another level of Fat Fuck...just worse
Say your boss pisses you off to the point in which the word fat or fat fuck, just doesn't settle with you. Fat Rat Motherfucker is pretty insulting, personally i don't think anyone would like to be called a rat or fat rat either, so Fat Rat Motherfucker just makes it more fun to say.
