Place it right after the reveal shot, once the insect is visible on screen, so it answers the moment instead of introducing it. Follow it with a Bruh reaction to close the joke, keeping the French callout as the centre of the edit.

This is a short spoken French line, just over seven seconds long, in which a voice names Ali Ben and calls something a cockroach. The delivery is plain and matter-of-fact, which makes the odd callout land as dry, silly humour rather than a serious accusation. It works as a quick, puzzling reaction that gets funnier the more out of place it sounds.
