My best friend went to Ozzfest; she said that the lead singer of one band dressed like a male porostitute and was walking around the stage buck naked for his last song, and people were making balloons put of condoms. And that she almost got hit in the head several times by clumps of dirt and rocks. And she got a Rob Zombie shirt and said he was awesome. Yeah.
I've never been to a real concert, woe is me.

Well, a Jimmy Buffet concert once, but that doesn't count since I was about 7.
