Place this clip at the reveal in a prank edit, right when the culprit is exposed. Follow it with a shocked meme sound for the victim's face, then an oh no no no laugh as the room reacts and the scene cuts away.
O tym dźwięku
A short 1.7-second voice clip of a speaker proudly announcing, in a sweet childlike way, that they have just done a boom boom, using the playground euphemism for going to the toilet. It lands as silly, shameless and a little gross, the humour coming from how proudly such a private accident gets declared out loud.
