Since "ball"ing is a common slang term for having sex, it means simply having sex outside in the snow.
My lady and I had a snowball last night. I don't know if it was the chill on the backside (initially shocking, but extremely erotic for some reason), or being outdoors under the moonlight that made us so excited.

Snowball ... s n o w b a l l. A snowball is when someone blows a load into your mouth but you don't swallow it, instead you share the cum with another person by spitting it into their mouth.
I was going to make my safeword snowball, but the first time I used it some dude blew his load in my mouth and some girl made out with me...
