The sound comes from Temu's Shop Like a Billionaire Big Game advertisement, where a bright cash-register chime underlined the app's promise of low prices and big savings. After the ad aired, the short clip was lifted by soundboard users and short-form creators who wanted a quick, recognisable money sound without recording one themselves. It spread through shopping hauls, deal videos and parody edits, where the chime works as shorthand for a bargain or a purchase. Because it is short, clean and instantly understood, it remains a handy punchline for spending, saving and online shopping jokes.
