4-LOM first appeared as one of the bounty hunters in Star Wars, later reimagined in LEGO form in the LEGO Star Wars video games. In those games characters communicate through short grunts, beeps and chatter rather than full dialogue, which gave droids like 4-LOM a distinctive set of electronic noises. Players recorded and shared these tiny clips on soundboards, where the second chatter variant became a reusable reaction sound. Its brevity and lack of words make it easy to reuse across edits, streams and memes without needing context, much like the Chewbacca sound.
