A sexual act, while someone in a Barney suit, wears a red strap on, and fucks a man in the ass, while the man that is receiving it is singing the barney theme song and jacking off someone in a squirrel costume (Scooter McNutty), all while someone in a BJ costume masturbates on the recipients face.
“Last night was crazy, turns out a dirty Barney is not what I thought it was”
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.
