The extended bruhh sound grew out of online slang rather than a single film, show, or viral clip, with bruh long used on social media as a shorthand for disbelief, disappointment, and secondhand embarrassment. Short audio versions began circulating on soundboards and in reaction edits, where the dragged-out delivery worked better than the plain word alone. It spread through gaming montages, fail compilations, and short-form videos because it is instantly recognisable even without context. That simplicity keeps it in regular use as a quick, low-effort punchline.
