It's usaully said "white hats". It's a term mostly used in the phish parking lots and "heady" scene to describe obnoxious preppy frat boy types there to party and not as much for the music. These are also the "kids" who will most likely spend $300 on ticket to a sold out phish show. They are a lot of times "custies" as well.

White Cap (verb): the act of cumming into a hat and placing said hat upon someone's (usually a female's) head.

The term comes from the "white caps" on waves, the white, foamy, uppermost part of a wave.
Dude 1: Lauren kept bugging me to let her wear my hat all evening, it was so annoying.

Dude 2: Did you let her?

Dude 1: yeah, but I white capped her. She didn't even notice till she went to take the hat off, and it was glued to her head!
