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".
