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.

the cutest little hub on earth.
best boy.
he might look like intimidating but he. is. not. he deserves the whole world.
not to mention that he is skilled. i mean his nickname isn't 'no touch service ace' for no reason.
definitely one of the best boys to ever exist
