Liane Cartman

Liane Cartman is (supposedly) the mother of Eric

Cartmans Abuse
She puts up with his constant whining and abuse by doting on him to the point of compounding his personal problems. She rarely raises her voice, and the only discipline she dispenses is a very rare slap to the face when Eric embarrasses her in public, an infrequent grounding (he was grounded for two weeks once for trying to exterminate the Jews), and an admonishment not to pick his nose (to which he insists he's only scratching it).

Sexual Appetite
Despite her sweetness, she is a hermaphroditic porn-queen and prostitute. Quite early on, it was revealed that Mrs. Cartman was actually Eric's father. Trey Parker named her after his ex-girlfriend who broke his heart.
