A doughnut performed when there is a layer of snow or ice on the pavement. Can be easier or harder to do than on dry pavement. Usually preferred by drivers of low-powered vehicles, because it easier to break traction, and puts less wear on the car and tires. Higher powered vehicles, especially rear wheel drive ones, will require more throttle control and steering skill than say a low powered front wheel drive one. Usually scoffed at by people who can do real doughnuts or drifts.
Some kid in his civic was doing snoughnuts in the parking lot yesterday.
