A stereotypical greener will have dreads, dress like a homeless person, smell like a wet dog who just smoked a pack of clove cigarettes, and live off of their mommies and daddies. In reality most greeners are very nice, clean, upstanding members of the community, their reputations are just sullied by the dirty hippies who are majoring in pottery.

Girl:"Hide their mom's credit card under a bar of soap."
That guy has a girlfriend but he doesn't tell anyone because he's on the lookout for someone better. He's such a greener.
