Get a girl naked..preferably one you dislike. Have her lie naked on the bed face down. Tell her you have to use the bathroom. While in the bathroom, shit just far enough out of your ass so the shit hangs a good couple inches. When you come out of the bathroom run and slide across her back like you would across the hood of a car.
I saw this Bitch i hated. So I decided to TURDlewax her!
A game that is best played while mildly constipated. To play, you must bend over in front of a person's face. With your anus muscles, push out just enough to reveal the end of a turd. The person behind you must say "peek a boo!" and push the turd back in with either their tongue or finger. Afterwards, it's their turn. The first person to either fart or accidentally drop the turd out of their anus, loses. If you quit due to anal pain, you also lose.
After we had a fulfilling meal, my wife and I decided to play Turdle Peek-a-Boo in the shower. I lost when I accidentally blew my wind on her face.
