Mongolian throat singing, known as khoomei, is a traditional vocal style from Mongolia in which one singer produces a low drone and a high melody at the same time. Online, short clips of that distinctive sound have been reused far beyond folk music, especially in memes and short videos where an over-the-top, ancient-sounding entrance is the joke. The five-second length makes it easy to drop into edits, and its unfamiliar, powerful tone still stands out against more common reaction sounds, which is why creators keep returning to it for dramatic reveals.
