A well-placed and extremely hard blow to the testicles. Done correctly, a nutbuster will incapacitate even the strongest man for several minutes. Best results are usually achieved with a kick, using the laces of any sturdy shoe. Other methods of nutbuster delivery include a baseball on the end of a rope, knees, or even a strong punch.
A nutbuster plus is a fat chick who likes it on top, and gets into it so much that she generates additional inertia and momentum and completely flattens your balls.
A style of facial hair also known as a soul patch. It's a small patch of hair on the chin just below the lip. It would be in the perfect position to dust off a set of nuts that would be on the man's chin as was performing fellatio.
