A person who advocates a particular relationship between two characters in a film or on television.
The term usually refers to unusual (e.g. homosexual) pairings but is not restricted to them.
So called because a slash mark ('/') is used to denote such relationships. e.g. Legolas/Aragorn
(1) I love non-normative relationships. I'm a big ol' slash bunny.
(2) I'd be a bunny for Angel/Spike.
