a group of losers that act like losers inside there own group to feel cool, but to others outside there group, seem like the biggest losers u you have ever met. these people tend to hang round in clusters and have a token girl amongst many guys. can be distinguished by constant quotes of comedies. ie family guy, simpsons, american dad etc.
a person that wears a helicopter hat thinking that they are being cool but are just being prosh.
