The exact origin of this elongated bye is not tied to a single well-known film, show or viral moment, so it circulates mainly as a generic goodbye clip on soundboards and in short-form edits. Its appeal comes from familiarity: almost everyone recognises the stretched farewell from everyday speech, phone calls and video sign-offs. Creators reuse it because it needs no context to be understood, and its brief length makes it easy to drop at the end of a clip. That simplicity helps it stay useful long after more topical meme sounds fade.
