Saying stuff like "Hails" and "Infernal Hails"
Old Pickup trucks with band stickers everywhere and more money in the speakers than in the truck...
Ripped up Jeans, Leather Biking Jackets, White & Black grease paint, Whiskey & Weed, Long assed hair (the longer the more metal), Denim sleeveless jackets with a bigassed backpatch of 'the trooper' style eddie, Anything having to do with thrash, especially guys in tightassed rolled jeans and white hightop reeboks with tattoos all over their arm and a grimace that would make a lesser man piss himself...
VIKING RAIDS!
