When a guy puts his stiff dick in the snow until its so cold it is totally numb and then shoves it in a girls warm pussy.
Carl and Liz fucking outside in the snow...

Liz(bent over): Come on baby get inside me...
Carl(dick in the snow): Hang on babe, when it comes it'll be worth the wait.
Carl with his dick totally numb and freezing cold quickly shoves his whole shaft in Liz's warm pussy. Liz screams out with pleasure and asks "WOW, What was that?"
Carl responds, that's a Boner Snowman.
