This clip is a loud, drawn-out human scream lasting about two seconds, with the voice rising sharply and holding at full volume before it cuts off. It feels sudden, panicked and over the top, the kind of shout that turns a small mishap into a dramatic moment. It works best as a burst of alarm or comic shock, landing instantly without any setup or words.
