The exact original source of this audio is unclear, so it is best understood as an internet meme clip built around the idea of a completely normal call that obviously is not. Sounds like this spread through reposts on short-form video apps, meme pages, and chat groups, where the contrast between a bland title and chaotic audio makes the joke land instantly. It is still used because the setup is flexible and recognizable, much like a buzzer moment or a bruh reaction.
