What does fubar mean?
FUBAR is an informal slang acronym standing for 'fouled (or f***ed) up beyond all recognition' — sometimes rendered 'beyond all repair'. It describes a person, thing, plan, or situation so thoroughly botched, damaged, or disorganized that recovery seems impossible. The word originated as American military slang during the Second World War, when soldiers coined a family of sardonic acronyms — most famously alongside SNAFU ('situation normal: all fouled up') — to capture the absurdity and frustration of wartime bureaucracy and combat. In modern usage it functions chiefly as an adjective ('the engine was fubar') but can also appear as a noun. Its tone remains resolutely casual, with a mild vulgar edge inherited from its expansion, making it common in military, technical, and everyday informal conversation yet out of place in formal writing. Its endurance owes much to its punchy rhythm and dark humour: few words convey hopeless dysfunction quite so memorably.
Hopelessly botched, damaged, or disorganized beyond all recognition or repair.
"After the failed migration, the database was completely fubar."
Almost always used predicatively or after the thing described; strongly informal.
The acronym FUBAR itself, or a state of affairs that is utterly fouled up.
"The whole launch turned into a total fubar."
Less common than the adjectival use; typically treated as an indeclinable borrowed acronym.
Born in the chaos of the Second World War, FUBAR joined SNAFU as GI slang that turned battlefield frustration into an unforgettable acronym — one so durable it now describes botched software launches and political debacles alike.

Etymology of fubar
FUBAR originated as American military slang during the Second World War, coined by soldiers as a crude acronym expressing exasperation at situations ruined beyond salvage. It belongs to the same wartime family of acronyms as SNAFU and TARFU, which circulated among US troops in the early 1940s. From military use it spread into general civilian slang, particularly in the United States, and later found a natural home in computing and engineering culture, where it is applied to systems corrupted beyond repair.
How fubar is actually used
Strongly informal and mildly vulgar; the expanded form contains an obscenity, though the acronym itself is widely considered acceptable in casual speech, military contexts, and even some workplace banter. Avoid in formal writing. Common in military slang and tech culture on both sides of the Atlantic.
