A person that isn't hot enough or cool enough to be a douchebag, but still tries. The only girls they can get are the Popular girl wannabes. And they'll try to be friends with real douchebags, but end up getting made fun of behind their backs.
Wannabe Douchebag: Hey guys! Had a date with a hot girl last night, if you know what I mean. -wink-
Douchebag #1: Uh cool.
Wannabe Douchebag: Nice hanging with you guys, but I gotta go pick up some chicks. -walks away-
Douchebag #2: Why does he talk to us again?
Douchebag #1: -shrugs- He's such a douchebag wannabe.
