When I was in the 9th grade, me and my best friend at the time were profoundly obsessed with Gwar.
We bought, borrowed, or stole every last album or piece of paraphanelia we could get our hands on, and we were waiting for a chance to go and see them. I remember hearing all these crazy rumors, about how suicidal people volunteered to be butchered on stage with the body parts being flung at the crowd, how people regularly got beaten to death in the mosh pit (that happened once at a Gwar show, and has happened several times at Slayer shows), how they would turn up the indoor heat to 150 degrees with some kind of furnace in order to simulate hell, how they sprayed the crowd with real human blood while lying to the authorities that it was fake, how they had full-blown ritual orgies on stage that lucky people picked from the crowd got to participate in, how you had to be well-connected to get into their shows because of how illegal it all was, and so on and so forth.
Hey, when you're thirteen and stupid... you're willing to believe just about anything that titilates so.
We memorized the entire Gwar mythos, as had been provided in liner notes and other materials. And we were always doodling in our notebooks and drawing pictures at home of the members of Gwar going on bloody rampages.
Yeah, we were obsessed. But as far as I know, the other dude wasn't an Aspie.
