The act of either orgasming due to the prediction of snow, or the act of achieving a large amount of snow in a short period of time.

Snow flurries may be called premature snowgasms.

Get the snowgasm mug.
when the snow on the way up to a ski hill looks so good it almost gives you an orgasm
or
when a run is absolutely amazingly awsome for example when you get first tracks on six inches of powder
"It looks snowgasmic out there"
