Place it at the end of a reaction edit, right after the claim it answers, then follow it with a Vine Boom for a heavier finish, or put a Dun Dun Dun before it when the setup needs more drama.
Über diesen Sound
This is a very short vocal clip, just under a second long, built around a single flat buhh utterance. It lands as a deadpan, unimpressed response, the kind of noise you make when something is boring, obvious or not worth a fuller answer, and its bluntness is what makes it funny in a chat or an edit.
