Noun. A logistical and psychological condition -- first observed in Denmark, Turkey, and France, and now spreading rapidly across the United States -- of general disorder brought on by sizable snowfall. The term must be set in italics or block capitals, followed by exclamation points, and accompanied by laughter.
The falling flakes brought total mayhem: King Kong was slipping and sliding around the top of the Empire State Building; delivery trucks loaded with cases of cinnamon chewing gum were almost completely submerged in white; the evening schedule of happy endings was thrown off by three hours -- SNOW CHAOS!!
