An acronym standing for fouled up beyond all recognition, originating in military slang but widely used in industrial and technical settings. It describes machinery that has suffered catastrophic failure, or a project that has gone so completely wrong that it cannot be salvaged. When a technician declares a part in this state, it means it must be scrapped and entirely replaced.
