Semi

The act of fisting your partner with 18 fingers, being 18 fingers for 18 wheels, generally putting 6 in the front, and 12 in the back, often requiring more than 1 person giving the Semi.

I hooked up with Sammy the other day, and she really wanted to bang, but 2 of my other friends wouldn't stop tagging along where we went, so she took my offer for a good ol' Semi, I hadn't seen her again until the obituaries in the newspaper, she died from being too loose, releasing her organs out of her body.
