A very sexual girl that doesn't realize she's being used for sex for a long period of time. A guy calling his girl his "Butterfly Pixie" is basically calling her his "cute little sex toy". She's abnormally stupid, and will do anything for love, even though she's only getting sex. She might think she's special, but of course, she never will be. The guy will just use her for sex until a better Butterfly Pixie comes along, or until he gets a real girlfriend.
