real metalhead
A person who knows they listen to real metal, but won't brag or rub it in people's faces. A real metalhead knows alot of bands, listens to either old or new ones, regardless if they're mainstream or underground. A real metalhead doesn't judge others by their appearance or bands they listen to. The way you dress doesn't make you a metalhead.
Dam. That guy is a real metalhead. He knows alot of bands and goes to shows and has a good time. He doesn't care what others think about his appearance.
