The act of taking a baseball bat and hitting someone about the knees, shins, ribs, head, or any other part of their body, in order to extract some cold-blooded retribution. Usually practiced by the mafia (or angry dads who just found out their daughters got boned by a dude they disapprove of) or anyone who wants to make a quick statement loud and clear.
Did you hear those c***suckers got what was coming to them? Vinnie just got back from ballbatting their knees after they ducked him for more than a year for the 5 grand they owed him!
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.
