After you are done jacking off, nutt into your hand and then run out of the room and slap your roommate right across the face with your cum filled hand.
Once I was done jacking off, I nutted in my hand and then I ran out and slap jacked my roommate right in the face!

The act of slapping your dicks together until one person gets a boner. The person who gets the boner wins the bet.

A "homeless" person who lives on the street.The one with no teeth,dirty as hell,and talks to himself outloud while making no sense at all.Sleeps on a piece of cardboard
In downtown San Francisco,you will see many "slapjacks" on the street during the "wee" hours of the morning.

A game similar to the classic punch buggy. Every time one sees a yellow vehicle, they slap the person next to them and say "slapjack!"
