The bruh sound comes from a long-running internet meme built around a weary, deadpan reaction to failure, while cartoon fart noises have been stock comedy effects for decades. Combined into a single one-second clip, the pairing became a staple of short-form prank edits, fail compilations and awkward moment memes, where the contrast between the tired setup and the crude payoff does all the work. Its brevity makes it easy to loop, layer under captions and drop into rapid-fire meme edits without breaking the pacing.
