A position in the Palma Sutra, the ancient discourse on self-pleasure, slopscotch is when you squat down and grab hold of your protuberance and hop up and down until release is attained.
When someone, usually drunk, puts their hand on the table and spreads their fingers out and uses a knife to stab quickly between them. Also known as the Knife Game.
"I cut the shit out of my fingers last night when I tried to play stabscotch, I really shouldn't drink so much"
