Place it immediately after the failed attempt in your edit, following a fail cue such as SpongeBob Fail and before any reaction shot. If you want extra drama, put Dun Dun Dun just before the reveal, then let this clip close the moment without adding another effect after it.

This seven-second clip is titled Defaite, the French word for defeat, and is filed as 'Motus Boule Noire'. It gives a flat, comic letdown, making a failed guess or a lost round feel instantly final and a little ridiculous. Its mood is wry rather than harsh, turning disappointment into a small shared joke for the loser and everyone watching.
