Nah.- play metal really loud and piss off your family/neighbors
Yeah, I do that. I wear metal shirts everywhere.- wear metal shirts to the grocery/laundry
Don`t have long hair. I actually did get it cut, since I looked like a hooligan with my semi-long hair.- whip your waist-length metal hair around the office and poke your coworkers in the eye
Nah. My friends know I like metal, but they`re indifferent enough towards it where I don`t try to troll them with it IRL.- try to make your non-metal friends like your music even if theyve told you repeatedly that they absolutely hate it
Don`t do this.- use death metal vocals in normal conversation
Nope.- other "hey im a badass metalhead" stuff?
