When you bend your girl over, stick a left over chicken nugget in her bumhole whilst guiding it in with your left thumb, with one leg over in the air as you slap her ass cheeks.
Diana : Hey baby what should we do with the left over nuggets....
Mirko: I think you know ;)
Diana : Ok, I will prepare my ass cheeks Mirko: Ok honey, I'll meet you in the garden for the MC Chicken Backslapper
Similiar to the "stranger," the act of masturbating with your opposite hand, backwards after sitting on it (so it goes numb) to simulate someone else jerking you off. Usually done in the dark so you don't realize its yourself.
"I gave myself a Chicago backhanderlast night since my girl was not available. It was like somebody else was doing it."
(Australian Slang - Western suburbs)... Reverse hand masturbation. Where the crevice created by the thumb and forefinger becomes the entry point for the bulbous member. Quite common in the western suburbs in Sydney (wanking capital of the world).
When you get permission from a female to ride her back naked, just as a jockey would ride a horse. Whilst the female is running the, gravitational pull causes you dick and balls to lightly brush her back.
