The exact source of this sound is unclear from the available metadata, but it is commonly treated as a short anime-style reaction clip. Its appeal comes from the odd phrasing and memorable repetition, which make it easy to drop into fast meme edits. Sounds like this spread through reposts, short-form videos and soundboards because they communicate confusion in a very specific, funny way. It remains useful because the line is brief, recognizable once heard, and flexible enough for reaction posts, parody edits and nonsense humor.
