A game enjoyed by the lordship of Bavaria from 1430 to 1505. It involved three naked men gathering around a circle 10 feet in diameter. They would run around the circle attempting to reach up from behind and tickle the person in fronts testicles. The last person to remain in the circle without laughing themselves to the ground was crowned the champion.
"Ludwig and I enjoyed a nice, friendlygame of Dandyballs earlier in the day. He tickled Luitpolds testicles so fiercely, he fell to the ground laughing and crying!"
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.
