Fruit Bat

Slang for a Narcissistic person. May look super cute and fuzzy but turns out they are a sneaky creature of the night that lives to flit from one place to another sucking the sweetness out of everything they get too close to.

That guy is a total Fruit Bat. He's hairy and cute but he sucks the sweetness out of every woman he's ever been with then flies on to the next one. Total narcissist.
