noun - A female who is assertive and aggressive in bed, but in a passionate rather than dirty or slutty sense.
adj. - When a woman is so good in bed that it's impossible to break up with her, because he knows no pussy will ever compare. A guy would sooner castrate himself than do something that would risk her breaking up with him.
1. Baby, I can't stop thinking about the way you drained my balls
last night. You're a fucking
2. Every guy who'd ever been with her was spoiled for all other women because of her femanimal abilities.
Dick: See that cougar
over there, I bet she's a monster
in the sack whether she's on top
, bottom or taking it doggy style
Harry: Yeah, she probably just got divorced and hasn't had an orgasm in like 10 years. That kind of deprivation can turn even the most unassuming woman into a femanimal.
