1.) An imaginary --or is it?-- creature which has the body of a woman, head of a cat, and wings of a nymph, or dragonfly. Catnymph are adept at luring men into their lair and making them do whatever the catnymph wants.
2.) A super-strong, sexy woman who possesses catlike abilities, such a being able to leap into the air, several times her own height, and always land on her feet. She has the ability to turn any mortal man into a cat at will by engaging in coitus with him. She is often in the company of many cats, several of which, you can be sure, were once human.
I had to give her my wallet. She was a catnymph.
