fuckup

A serious mistake.

Forgetting our anniversary was a major fuckup.

The gate was high; it had been a nine-foot drop; she had landed wrong and broken her arm. Oh Jesus Christ, what a fuckup.

One who continually makes mistakes; a person who fucks up a lot.

You've got to fire that fuckup.

I can't believe she's dating that colossal fuckup. All he does is yap about baseball.

A mentally or emotionally damaged person.
