Bip Bup has no confirmed single origin, and it circulates online as a short, generic electronic blip rather than a line from a film, show, or game. Sounds like this spread through soundboards and meme editors because they are instantly recognisable, easy to reuse, and small enough to fit between dialogue or music. Creators use it as a notification cue, a reaction to something cute or surprising, and a way to mark a visual change. Its appeal comes from its brevity and cheerful tone, which make it useful in short videos, streams, and chat edits without distracting from the joke.
