GoPay is a digital wallet widely used in Indonesia for everyday payments, top ups and money transfers, so its notification alert is a familiar everyday sound for many phone users there. As short app sounds began circulating on soundboards and in prank videos, this alert was shared on its own, separated from an actual transaction. People now play it to imitate an incoming payment, joke about a transfer that never happened, or get a quick reaction in social clips, which explains why a simple notification has become a prank staple.
