Dude 1: "Isn't being a metal fan awesome?"
Dude 2: "Except for the headbang hangovers, yeah."

Hangover Headband

A stretchy or elastic fabric worn on the head to conceal the unshowered, nasty hair of an individual after a night of drunken debauchery.

Molly: So...did you go out last night.
JIll: Yea...can't you tell by my hangover headband.
