Did you hear that the Virginia GOP put out an ad mocking the snow storm as "12 Inches Of Global Warming."? I can't believe the snopidity of some people.
A combination of snow and stupidity. Dumb things people do when it snows.
Sledding into traffic, driving too fast (or too slow) for conditions and causing a wreck, naked snow angels, etc. "He drove with a fair amount of snowpidity".
