Cash register sounds have been a shorthand for money in cartoons, sitcoms and game shows for decades, long before they became a staple of short-form video. The drawer opening and bell became instantly readable even without dialogue, which made the clip easy to reuse across languages, including Portuguese uploads titled caixa registradora abrindo. Creators now drop it into hauls, business jokes, sales announcements and reaction edits because it communicates profit or success in about two seconds, without needing a caption or explanation.
