slips up
Makes a blunder
To slip up is to make a careless mistake or error in judgment.
The expression suggests a minor stumble rather than a catastrophic failure—the kind of blunder that happens when someone loses focus or acts hastily.
Everyone slips up occasionally; the important thing is how you recover.
A slip-up is the noun form, denoting the mistake itself.
