Place this clip right after the visual reveal in your edit, then follow it with the oh no no no laugh for a longer payoff, or precede it with a shocked meme sound when you want the reaction to build in two steps.
About this sound
The clip is a short voice snippet of someone saying Oh Nono in a hurried, drawn out way, like a refusal that keeps repeating itself. It gives listeners a mix of panic and comedy, the feeling of watching a small mistake turn into a bigger problem while someone desperately tries to stop it from happening.
