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.
Noun. A sorry clustering of nubs, usually in a PVP gaming environment. Usually the chief indicator of an inherently weak team. Similar to turtling, except that the former can be a valid PVP team strategy in some situations. Nubclusterfucks, however, form when the majority of PVP team members are unfamiliar with the map (or PVP in general), are quickly routed, and fall back into a defensive position that guarantees they will not have the resources to acquire and hold any sufficient strategic advantages or objectives.
"Wow...what a nubclusterfuck at the Farm node. This AB loss is going to take an hour, I'm going /afk".
