I knew a kid in high school who said he was in a death metal band. He had snakebites and wore deathcore shirts. His hair was like mid back but that was the only thing even remotely metal about him. He used the fact that he was allegedly in a death metal band to fail attempt to pick up ugly girls constantly.
Now normally i'd grant that he was like 15, except I saw him in a music store the other day working in the acoustic section, he still seems to only know how to play an E and he looks exactly the same.
The metal scene was huge in my high school. From thrash to black and death metallerz. Among them, we had a few bands and would throw backyard shows and parties. The school held battle of the bands, my band won one year, no joke. But there are also a lot of hardcore s**t.
