This clip is commonly used online as a Japanese-style verbal reaction to confusion, disbelief, or something that makes no sense. Its short length suits meme edits, reaction compilations, chat screenshots, and comedic video pauses. The sound does not need a detailed explanation to work: the questioning delivery communicates skepticism almost instantly. It continues to appear in short-form content because creators can place it after a surprising line or visual and create a clear comic interruption without changing the surrounding audio.
