phrase used to describe a "bucket hat" when worn by custies, mooks and f-ed up frat boys. In a crowd of beer guzzling abercrombie wearing mooks, there will always be one wearing the hat in question.
"Some fratboy threw his Dude party hat on stage at the Dave Matthews Band concert."

Me: I'm having a dude party!
Friend: A party just for dudes?
