99% of people riding four wheelers are quadtards. They usually do not wear helmets and have a cigarette dangling from their lips as they try to look cool by doing donuts in the pits. They are known to go the wrong direction on the track and are often intoxicated. Most people with truck nuts (those fake scrotums that hang from the trail hitch) also have four wheelers. Quadtards are also know to do wheelies on the street and run extremely loud and obnoxious exhaust systems.
Did you see that quadtard at the track on sunday? He was doing donuts in the pits and slammed on the brakes on the face of a jump and Dave nearly slammed into the back of him
