The origin of this clip is a mystery even to most users: it was uploaded to a user-generated soundboard under a joke title and spread simply because the name makes people click. At just over ten seconds it is far too long for a real alert, which is part of the joke, and people use it the way they use other silly ping sounds like the Discord notification and the MLG air horn: as a punchline that interrupts streams, group chats and prank videos. Its staying power comes entirely from the title, which promises the dumbest notification ever made.
