Place it at the peak of the joke, after the setup line and before the reaction shot. Pair it with an instagram thud underneath for weight, then follow with a shocked sound on the cutaway so the sequence reads hit, impact, disbelief in that order for viewers.

This is a short, roughly nine-second clip built around the Italian phrase Le Mazzate a Peschici, presented as a loud prank-style button moment. It lands as rowdy and exaggerated rather than serious, giving a listener the feeling of a joke scuffle breaking out suddenly for comic effect in an otherwise ordinary conversation or video scene.
