This page is about the slang term fuck-up
a serious mistake
- There's been a major fuck-up in delivering the shipment. Some idiot sent it to Austria instead of Australia.
- How could a fuck-up like this happen? You told me you always double-check everything yourself.
Warning! This is very bad language. If you are a non-native speaker, you are advised not to use it. (You could cause resentment or anger if you use it inappropriately.)
