(Originated from the movie, "Mean Girls".) A group of popular,sophisticated girls. Rumors and gossip surround their daily lives. One doesn't become a plastick, it is what they are born to be. Their tight clique can be confused for being snotty people, even though they go by the persona of "hard,cold,shiny plastic!". They're just like the next girl, only a level higher.
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.
