Military term for an operation in which multiple things have gone wrong. Related to "SNAFU" (Situation Normal, All Fucked Up") and "FUBAR" (Fucked Up Beyond All Repair).

In radio communication or polite conversation (i.e. with a very senior officer with whom you have no prior experience) the term "clusterfuck" will often be replaced by the NATO phonetic acronym "Charlie Foxtrot."

5.
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."
