The act of fucking up so bad that it somehow results in something equivalent to being fucked from behind into the ground by a horse while a pack of kittens vomit all over the back of your head, generally occurring when missing a mark.
The other night I took this girl home from the bar but it turned out she was a dude and I had sex with it anyways. The next morning the dude woke me up and said "I'm leaving now baby cakes, I hope you didn't mind pulling a shima last night - my bad."
