Kassakone is the Finnish word for a cash register, and this clip captures its best known noise, the ka-ching that English speakers have used for decades to imitate bells and a spring drawer. The sound became a stock effect in cartoons, adverts and comedy sketches long before short video, because audiences already linked it to shops and spending. Online it survived as a soundboard staple, added to memes about getting paid, selling items, finding bargains or spending too much, where one short ring replaces a whole explanation about money.
