F***ed Up beyond All Recognition. Generally used in the context of a
situation/operation/
mission that is messed up so bad it is beyond salvaging. FUBAR comes after ATFU. Also generally used when describing
something that is akin to a Monkey S*** Fight.
When I started working for this company, I
just figured their M.O. was
SNAFU, however, after a few months, I realized they were just ATFU, now given their current
state, they are FUBAR.
