Place this clip at the cut point after the mistake, then follow it with the emotional damage meme sound for a bigger reaction or the oh my god bro hell nah clip when the fail needs a second voice.
About this sound
This is a 0.8-second clip of a man saying the single word 'bruh' in a low, flat, deadpan voice. It lands as instant disbelief and disappointed disapproval, like a verbal facepalm for a fail or cringe moment. It comes from a May 2014 post by CallHimBzar, using Headgraphix's voice over footage of Tony Farmer in court.
