This sound is mainly known through short meme edits online rather than a clearly documented original source. It spread in videos where a skeleton runs across the screen as a visual punchline, often combined with oversized eye emojis placed on people in the clip. The format became popular because it compresses shock, silliness and motion into a very short beat that fits reaction edits well. It still gets used in fast-paced meme videos whenever creators want a bizarre interruption instead of a standard reaction sound.
