This clip is associated by users with Horimiya, specifically episode 12, and has spread online as a short anime reaction sound rather than a long quoted scene. Creators use it for edits, captions, and comedic timing when a character looks overwhelmed or confused. Its popularity comes from how clearly the voice communicates surprise in under a second, making it easy to sync with visual punchlines. It remains useful because anime reaction audio travels well across short-form videos, especially alongside other awkward moment style sounds.
