Pixie; common slang often used when referring to someone as gay, or if in the case of a male, effeminate. Most commonly used as British slang, it's a renewed edition of the slang word 'fairy' which is an old word referring to someone who's a homosexual. Most generally used as derogatory speech from bullies or assholes.
Bully 1: God, look at him- he's such a fucking pixie isn't he?
