A word used to describe someone who is having a stupid moment. It was created in New Braunfels by two girls who needed to find a different word than "retard" because the word "retard" was thought inappropriate by their parents and teachers.
"Jill is such a gimtard. I can't believe that she thought Washtington DC was in Washington state!!"
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.
