A young child who is witness to and or propagates inappropriate-for-age, yet humorous, situations or comments of a sexual and/or perverted nature--most generally unwittingly.
Refers to fictitious 7 yr-old character in TwitterBones/Twones fanfic, @ParkerBooth, who is NOT affiliated with Fox and/or Bones TV show.
Did you see the little pervker ask his daddy to show him how to make his pants go "bump" in the front?
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.
