A situation that is totally fucked up, especially as a result of managerial incompetence.

Originally of military origin; a double play on the word "cluster," both evoking multiple fuckups, as used in the term "cluster bomb," and evoking the oak leaf or star "cluster" insignia of the REMF who did the fucking.
Military: "Fuck, I heard Wilkins bought it last night going into that 'headquarters building.' The fucker was shit empty except for the IED that blew him to hell. Took two other guys' legs off and shit. Whose goddamed idea was that whole clusterfuck, anyway?"

Civilian: "That Big Dig is a complete clusterfuck from end to end. Over budget, over due, and now under water."

Incorrect, but sounds like fun: "The three of us got together and clusterfucked all night."

Marine slang -- A clusterfuck was any group of Marines big enough to draw enemy fire, or several Marines close enough together to be wounded by the same incoming round. More generically, a clusterfuck was something that was all screwed up. Whenever three or more CAP Marines gathered in the open, talking or working on something, somebody was sure to call out "clusterfuck!" and one or more guys would walk away.
