and for you americans, THAT would mean:
"He'd be really hot if his hair got cut with some scizzies, ain't that right cowboy?"
Hah, jokes about the cowboy babes. But above is true.
Being taught the proper way to preform an action, via extreme ownage and embarrassment. This requires the scazzy, who is always of such a high level of skill that the non-scazzy has no chance of saving his reputation, to utterly dominate and show no remorse. If remorse is shown, it is done in a cool and laid-back way, as in to say "Your not even worth the effort of my pinkie finger", which ironically is just as brutal as an all-out ownage.
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.
