A metal Head is anyone who listens to, and loves metal music. Sub-genres are not a factor. Clothing is not a factor. Whether you hate everything is not a factor. Whether you just like the older metal bands, or the newer ones doesn't matter either. To be a fucking metal head, all you have to fucking do is love metal music. Thats fucking it.
Me: i fucking love metal!
Someone else: he's a metal head!
