a quick and audible fart aka a bird fart. the only noise it makes is 'Ernt'. Sometimes happens whilst sitting on a stool, trying to force a big one out, having to fart so bad that no matter how hard you try to hold it in you accidently let a little one go

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.
