Over the top fans of the Vampire series "Twilight". The kind of person who stands in line all day to get in to the midnight showing of the latest Twilight movie. Most likely they have read all the books and have picked a side... "Team Edward" or "Team Jacob." These people sometimes call themselves
Dude 1:Hey, so we going out clubbing tonight?

Dude 1: Wow, I never pegged you for such a Twi-tard!
