o'weener - An o'weener is a f***ing grown-up who still wants free candy

An o'weener is a f***ing grown-up who still wants free candy. They are like the kid who still asks for dessert even though they are full.

My aunt wore a princess dress and got candy from kids who didn't know who she was.

My uncle wore a vampire costume and got chased by a kid who thought he was real.

My cousin dressed as a ghost and got candy from a kid who screamed and ran away.
