You named your cat Dammit?
Well... yeah. Mostly because she's a feisty puss, and when she gets playful she tends to go no holds barred. It usually results in one of us saying "OW, dammit, cat!" It just evolved to her name being Dammit. She's a sweety though, when she wants to be. When she was a kitten she was just as "I want to disembowel your hand" ish.
