The clip comes from Super Danganronpa 2: Goodbye Despair, the visual novel sequel first released in Japan in 2012. Mikan Tsumiki is the Ultimate Nurse, a timid student known for stammering apologies and panicking under pressure. Fans clipped her flustered lines for soundboards and fan edits, where this short wait became a shorthand reaction. It spread through anime and gaming communities alongside other reaction sounds like the bruh meme, and remains popular because the panic is instantly understandable even to viewers who have never played the game.
