Snowball Slalom
When a man ejaculates down a girl's crack, only to have himself or another individual lick it off and spit it back down another person's crack, only to have it licked off again, thus being "snowballed". Repeat as necessary or often as desired. A variation of the popular snowball.
Sarah came over to visit, but Megan was here. Somehow we ended up drunk and I ended up engaging in the sport of the Snowball Slalom. Megan didn't rinse her mouth afterwards...
