Place this clip right after the visual reveal in your edit, then follow it with a fail sound meme button for the aftermath, or precede it with a bruh meme sound button when the bad idea is first announced.
About this sound
This clip is a brief burst of ahh, ohh and ahah vocal reactions lasting about 1.2 seconds. It feels disgusted and amused at the same time, like watching something revolting unfold at the table. It comes from the Dinner Made by Hand scene in Scary Movie 2 from 2001.
