When it is snowing so damn much you cant even see a thing.
OMFG, it's a fricken snownami outside!

A tidal wave of heavy, packed snow, plowed onto your driveway by a city snow plow truck, and usually just shortly after you have spent a couple of hours shovelling out your driveway by hand.
Man, that city public works dude almost buried my Honda with a snownami...
