Among the more well-known of military slang words are snafu and FUBAR. Both originated in WWII. Snafu has since passed into regular language use as a noun meaning a mess, an unexpected monkey wrench thrown into one’s plans. Originally SNAFU, the letters stood for Status Nominal: All Fucked Up, a sarcastic term referring to the normal chaotic state of military life in the field.
FUBAR, in contrast, still keeps its acronym status, which means Fucked Up Beyond All Recognition. Both terms have polite definitions in which “fouled” is substituted for the “fucked.”
