act a fool

Behave like buffoon

To act a fool is to behave in a wild, reckless, or uninhibited way—often deliberately and usually in a social setting.

The phrase suggests abandoning restraint rather than genuine foolishness: We're going to act a fool at the club tonight.

It can be celebratory or warning: Don't make me act a fool up in here.
