Eric Theodore Cartman...aka Fat-Ass is one of the main characters in the animated series, South Park and is voiced by Tray Parker.

Cartman is the only boy in the series who does not have a father shown at any time. This is because of his hermaphrodite mother, who actually had sex with a woman, thereby fathering him.

Cartman is generally portrayed as a spoiled, foul-mouthed, sadistic, ill-tempered, insensitive, sociopathic, lazy, manupulative, greedy and racist. He despises Kyle because of his Jewish background and make fun of him for being Jewish. Even though he hates them, he still socializes with Kyle, Stan and Kenny because he seemingly has no other friends. He frequently bullies and teases his friends with great focus being on Kyle and he spares no sympathy for Kenny coming from a poor family.

Some of Cartmans popular catchprases are:
"I'll kick you squah in the nuts"
"nah nah nah nah nah naah nah, heh heh heh heh hehh heh!"
"respect my authoritah"
"I'm not fat, I'm big boned!"
"Screw you guys, I'm going home!"
"But, mooooooooooom!"

Cartman is so awesome.

In my opinion, some of his best performances are in the episodes:

TSST (the dog whisperer)
AWESOM-O
Casa Bonita
Die Hippie, Die
The Death of Eric Cartman
Fat Butt and Pancake Head
