Snow Cannon
A sexual act in which a man ejaculates into a woman's vagina while she is laying on her back. He then places his face in front of her open legs while she quiefs, spraying the semen onto his face.
The force of the snow cannon she gave him knocked him off of his feet.
Cadet Snow-Cannon
A Cadet Snow-Cannon is a dick-shapped snow-sculpture with a hose running up to the "cock-head" that, when turned on, shoots, sprays, and then dribbles out down the shaft - a snow-gasm! sno-cum everywhere!
Matt and I built a Cadet Snow-Cannon - we jacked off in the snow and shot our own sno-cum down each other's throats!
