There is no single documented origin for this laggy sound, which circulates as a generic user-uploaded effect rather than a clip from a known show, game or meme. Sounds like this became common as streaming, video calls and online gaming made connection jokes part of everyday humor. Creators reach for it whenever a visual gag needs an audible freeze, a robotic stutter or a fake disconnect. Its popularity comes from being instantly recognizable: almost everyone has heard a call break up exactly like this.
