Usually shouted at owners of rear wheel drive cars,
“Does she go round?”
“Does she hoop?”
“Can you diff her?”
“Can you do doughnuts in your car?”
A doughnut or donut is a maneuver performed while driving a vehicle. Performing this maneuver entails rotating the rear or front of the vehicle around the opposite set of wheels in a continuous motion, creating (ideally) a circular skid-mark pattern of rubber on a roadway and possibly even cause the tires to emit smoke from friction.
