A total faggot who isn't sure whether he's a gangster or a chav, therefore he listens to both types of music (Rap & MCing) when necessry in order to fit in with the pack. Also could be a term for loner, who would do anything to fit in and make friends.
"Hey, look at that loser, he thinks he's so cool listening to that chav crap."
"I'm sure he was listening to fiddy yesterday in the ghetto."
"What a chavster!"
