A very beautiful, sweet, slightly crazy texan woman with a heart of gold, who tells you she loves you, but then breaks up with you every other week. The first time she comes over for dinner, she'll drink a whole six-pack, and pass out on your sofa, leaving you to eat alone. Says "sheeeit" alot, and always announces when she has to go pee.
If it weren't that she were such a whackadoo, I'd probably still be with her.
