SNAFU is an acronym that is widely used to stand for the sarcastic expression Situation Normal: All Fucked Up. It is a well-known example of military acronym slang; however the original military acronym stood for "Status Nominal: All Fucked Up". It is sometimes bowdlerized to "all fouled up" or similar. It means that the situation is bad, but that this is a normal state of affairs. The acronym is believed to have originated in the United States Marine Corps during World War II.
