This clip comes from a user-generated soundboard, where it is tagged as a meme and listed under anime and manga, even though its appeal is mainly as a short reaction sound rather than a scene from a particular episode. Its brief length and instantly readable cute-but-suspicious tone help explain why it has been picked up for edits, streams and reaction videos, where a few seconds of character personality can carry a joke. It sits alongside other short anime vocal clips such as anime ahh, which work in the same way as quick, expressive punctuation for a visual gag.
