I can't possible imagine... Please someone enlighten me...

I believe its when a girl has your cum in her mouth and gives it to you through a kiss. I could be confusing it w/ somethin else, though.

Snowballing involves the transfer of semen orally. I have no clue what snowblowing is about.

Snowball?

quote:Snowball

Ah yes, every man's worst nightmare, the dreaded snowball. This happens when a girl blows you and spits the jizz in your mouth. Another definition is when a girl blows some other guy, and then gives you a hot sloppy kiss with some of that guy's fresh jizz still in her mouth. With all those dirty broads out there, odds are it has happened to you. Just ask your friends if it has, cause they probably already know and have been laughing their asses off at you.

Snowblowing? It's what Snowmen long for & forever dream about.
