An offensively large dump. A crap of such grave proportions, that should the cruel bastard decide to deliver it whole (without any effort of pinching it off, flushing in between), such a deed would amount to nothing less than an act of pure, unabated vandalism; a destruction of public or private property, with due compensation and mandatory letter of apology to the caretaker of said toilet.
Accomplice: Where ya goin?
Offender: Just poppin' into the loo to squeeze out a fat rat.
*closes door*
*speaking through the door, the conversation continues*
Accomplice: Have you prepared you're letter of apology?
Offender: Aye, writing it on the walls as we speak.
"The fuck?! Who broke my toilet? Whoever just laid this brick, fess up now, or when I find out, I swear I'll shove this fat rat back up your cursed cornhole so far, you'll be belching farts for the next week and a half!"

A Guinea Pig... A vile little creature that resembles nothing so much as a rat, if that rat were designed by GM and built by AMC.
Mom: So... Would you like to get a pet?
Kid: Sure. Anything but a fat rat.
A: What -is- that smell?
B: Oh, that's my brother's fat-rats. He changes their litter about as often as he showers.

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.

Also abbreviated to FRB, a fat rat bastard is an obese dirtbag who is the epitome of white trash. They sit on their asses the majority of the day and prefer budweiser as their beer of choice. Sweat accumulates in their belly buttons, groin, armpits, and the area between the man boobs and beer gut.
