A snow angle is when a girl lays down on the floor and starts to do the snow angle motion (you know... the arms and legs stuff) and as she is doing that, the guy cums all over her.
When a dude freezes a large amount of his semen until it's like snow with frost around it, and then you make semen snow angels in the frosty frozen semen.
"Let's make some semen snow angels."
"Me and my Hoemie are bout to make some semen snow angels."
"How about you come with us to make some semen snow angels the cum is freshly frozen."
Derived from german GGG films, this is the term for when a man ejaculates onto or into a womans butt and a woman removes the semen with only her mouth then spits the sperm back into the origianal recipents mouth.
