Worse even than SNAFU (which see), FUBAR is rendered, for polite company, as Fouled Up Beyond All Recognition. (Using "fouled" instead of f***ed.) FUBAR is not to be confused with community member FooBar, a delightful and beguiling creature created by Holly Lisle, site host, to test menus, systems and other working parts of the site. See FooBar's on-site bio! (Kay House)

Fouled Up Beyond All Recognition (internet acronym)

Fowled Up Beyond Repair. Meaning a game or situation is broken or ruined. Everything has gone wrong. "Retreat. Our attack on their base is totally FUBAR!"
