FUBAR is a military slang acronym that stands for "Fucked Up Beyond All Recognition" or more mildly, "Fouled Up Beyond All Recognition/Repair." It describes a situation, mission, or event that is completely and irreversibly messed up or chaotic

. The term originated during World War II among American soldiers and was used to characterize missions that ended disastrously, often with severe consequences

. The word may derive from the German "furchtbar," meaning terrible or dreadful, which aligns with the sense of something being disastrously wrong

. FUBAR has since entered popular culture and is used broadly to describe any situation that is badly broken or beyond repair

. In summary, FUBAR means a state of total failure or chaos, beyond any hope of fixing or recognition.
