Someone who attends the Evergreen State College in Olympia, WA.
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: "What's the quickest way to starve a greener?"
Guy:"I don't know."
Girl:"Hide their mom's credit card under a bar of soap."
