Place it just after the failed reveal in an edit, then follow it with a Vine Boom for a heavier punch, or lead into it with a Dun Dun Dun when the disappointment is about to land. For a lighter run, pair it with a SpongeBob Fail first and let this clip close the sequence.
このサウンドについて
This is a roughly two-second vocal clip built around a single long, breathy fahhh, held and stretched until it runs out of air. It lands as a weary, over-it sigh, funny because it sounds far too dramatic for whatever just happened, with a flat, resigned edge that makes the frustration feel shared.
