Place this clip at the punchline of a fail edit, after a shocked meme sound for the reaction and before an oh no no no laugh to close the sequence, letting each beat finish before the next starts.
About this sound
This clip lasts just under six seconds and pairs a long, drawn-out FAHHHHHHH shout with a fart effect washed in heavy reverb. The shout stretches out before the crude fart echoes underneath it. It feels absurd and deliberately over the top, funny because the echo makes a silly noise sound huge and dramatic.
