acted the fool

Behaved like buffoon

To act the fool is to behave in a silly, reckless, or undignified way—clowning around, making a spectacle of yourself, or doing something foolish you might later regret.

The phrase often carries mild reproach: Stop acting the fool and pay attention.

It can describe deliberate playfulness or genuinely thoughtless behavior.
