This clip comes from a voice changer tool, as credited in its file metadata, and is labelled as stuttering, which describes its broken, repeating delivery. Short glitch sounds like this became a staple of online horror and meme editing because they are easy to drop over a reaction, a game clip or a distorted character moment. At under two seconds long, it fits the fast pace of short-form video, where an unsettling noise can change the mood of a scene without dialogue or music. Its popularity comes from that versatility rather than from any film, show or viral trend.
