Snowball 

When you take a cold shower, or rub ice cubes on your balls, causing them to shrivel up and become hard. The testicles then become weapons used to break a nose (Of your girlfriend). When coupled with a Zombie Mask they form a One-two punch.

Snowball 

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.
