This is a short French spoken exclamation, lasting about 1.6 seconds, delivered as a sharp scolding line that says someone should not have done what they just did. It feels funny and pointed at once, like catching a friend in the act and calling it out before they can explain. The quick, emphatic delivery makes the rebuke land as a joke rather than a real argument.
