What are you doing that'll "weird out" a metalhead?
I'm a pretty big metalhead, And there's very little that will get to me. Unless, like, You're next to me, Blaring "Pink Cigarette" by Mr Bungle, and rubbing my leg.
...although at that point, It would depend on my level of intoxication/stone. I may grab yer ass and sing the song while looking into your eyes if you did that.
