This sound belongs to a broad family of anime-style vocal reactions that circulate online without a single credited source, which is why it is usually shared as a generic anime girl effect rather than a clip from one named show. Its breathy, exaggerated delivery fits the playful tone of meme culture, and prank creators adopted it early because it can turn an ordinary reaction into something cute or awkward in under eight seconds. It remains popular in short-form video because the reaction is instantly recognisable, even to viewers who do not watch anime.
