Place it right after the fail lands in an edit, then follow it with Brother Eww for extra disgust and Nelson Ha Ha to turn the embarrassment into a shared laugh.
About this sound
This clip starts with a bruh stretched out in disbelief, then rolls into several seconds of loud, wet cartoon fart noises, lasting just under twelve seconds overall. The deadpan groan followed by crude, over-the-top flatulence feels silly and gross in a playful way, turning a failed moment into a joke about disgust and bad timing.
