a rocker guy with a mullet or just really long hair, ripped jeans, tight shirts, and aviator sunglasses. Good derds like trucks with tanky accessories, like skid plates, winches, rollbars, etc and old sports cars (like camaros) with tweaked engines. pounding out 80s rock including AC/DC, Def Lepard and GNR at all times. Torque talk is common, as is fixing things whether the derd knows how to fix it or not.
"fuck, my older brother's the biggest derd. he crashed his mustang last weekend when he was drunk so now he has to drive his pick-up everywere. that things got an 8 inch lift kit, it's fucking huge. but he won't even miss the 'stang cuz he's fixing up an Iroc and that things gonna be a bitchin camaro when he's done with it. he's got a 12 disc changer in the back mang."
