The rururururu clip spread as a generic soundboard and meme audio rather than from a single identifiable film or show. Its appeal is the simple repeated syllable, which needs no context or language to understand and can be pasted into almost any video. Short looping vocal noises like this became popular in meme edits and group chats because they signal confusion, boredom or playful mockery without dialogue. It remains used for reaction posts, edits and prank messages where a meaningless, drawn out sound says more than words.
