The act of having sex then taking a dump. Extradited from the movie "Kingpin" from the scene where Woody Harrelson is forced to have sex with his unattractive landlord, after which she says "What is it about good sex that makes me have to crap?"
I couldn't help myself. I had to shit before sex, she was ready to go; so I took a Kingpin.
the adjustable bolt through the bushings and hanger of a skateboard truck that hold these parts to the baseplate.

when tightened, the skateboard does not turn as easily.

When a woman is held like a bowling ball, with one finger in her vagina and another in her anus. One of the fingers must be a thumb. NOTE: Switching fingers is unsanitary and could lead to infection.
Greg had his thumb in her vagina then slipped a finger in her anus. She screamed, "kingpin" and continued to enjoy herself.
