An humongously large motherfuckin asshole that acts like a buttwhipe Cleaner (buttwhipe cleaners are very dirty whores that only like to clean asshole)
Sarah: Hey, that black guy that fucked me last night, ye he's such a buttwhipe cleaner. He only liked my asshole the whole night!
Rachael: Ye, same with my white ass boyfriend. I was expecting some squirts and extreme ramidge to my pussy. But all he did was like my shithole.
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
