Cock Up
Cock up means a botched mistake, a messy failure, or a plan that went wrong in a pretty obvious way.
It is the kind of phrase people use when something should have been simple but turned into a mess. You will hear it in casual British and UK-adjacent speech, usually with a mix of annoyance and dry humor.
Saying it makes the mistake sound less dramatic than a full meltdown, but still clumsy enough to deserve a callout. It signals, "Yeah, that went badly, and everyone knows it".

What People Mean When They Say Cock Up
A cock up is a screw-up with visible consequences. It can describe one bad mistake, a failed plan, or a whole situation that got bungled.
People often use it for everyday chaos: a missed deadline, a ruined event, a broken process, or a dumb error that should not have happened in the first place.
Where Cock Up Lives Now
This phrase shows up most in UK conversation, office talk, group chats, and comment sections where people are being blunt but not overly formal. It feels more natural in British English than in US slang, where other phrases usually carry the same job.
It works best when the speaker wants a plain, slightly cheeky label for failure. In a serious setting, it can sound too casual; among friends or coworkers, it lands as sharp, readable shorthand for a mess.
Real Examples of Cock Up
