The chime itself comes from Apple Pay, the contactless payment system built into iPhones and Apple Watches, where a short ding confirms a successful tap. Online, creators took that everyday notification and boosted it far beyond normal volume, turning a familiar confirmation into an exaggerated meme sound. It spread through soundboards and short-form videos, where the louder version signals overspending, a flex purchase, or a joke about money disappearing instantly. Its appeal is recognition: almost anyone with a phone knows the original, so the louder twist lands immediately without explanation.
