Put it at the end of the failed moment, after the take or miss has fully landed, so it closes the scene. Follow it with the Nelson Ha Ha for extra mockery, or lead into it with the Wrong Answer Game Show sting when the fail is a bad answer.

This six-second clip layers a loud crowd boo over a voice shouting 'boo this man', turning a single call-out into a full audience verdict. The booing swells fast and sounds staged rather than angry, so the disapproval feels funny and over the top instead of harsh. It works best as an exaggerated reaction to a bad joke, a failed attempt or a terrible opinion.
