HDB
Referring to a guy: Hot Douche Bag

Referring to a girl: Hot Dumb Bitch

It seems the hotter people are the dumber they get. Attractiveness and intelligence has to somehow be correlated. Let's just be honest, the uglier ones try harder.
Ashley: Hey Britanny, meet any guys at the club last night?

Britanny: No, they were all HDBs. What's new, all the hot ones are either, dumb or assholes.
