Bruh grew out of internet slang into one of the most reused reaction sounds on short-form video, where a single word can carry an entire response to a fail, a bad decision, or an unexpected reveal. Its popularity comes from its versatility: it works in gaming clips, comedy edits, sports bloopers, and everyday vlogs without needing explanation. Because it is so short, creators can drop it into fast-paced edits without breaking the rhythm, and viewers recognise the joke instantly. That simplicity has kept it in circulation long after many louder meme sounds have faded.
