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.

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.
