Ahhh, the memories - I was also a "headbanger"....uh, wait - I still am Annnyway - I spent most of my high school years smoking pot behind the auto shop. I hung out with a broad mix of people - all we had in common was weed - from rap kids, to punks, to headbangers, to skaters, to goths, we alll smoked together.
As far as popularity - I'd say we were the leaders of the losers. (I'm sure all the losers say that!) If the situation called, we could muster quite a few losers to our cause.
It's funny, but at our school, you were defined by the table's you sat at in the "commons" - there were the jock tables, the popular tables, the chearleeder tables, the skater tables, the trenchcoat tables(long before any of this school shooting crap - ours were more into Weird Al and Dungeons & Dragons) a couple punker tables, and a few odd loser tables - and us, the "metal" tables.
Looking back, it's crazy how segregated we were - all the fights, all the bs...
