The clip is circulated online under the Russian label for a scary lullaby, which explains its odd appeal: a bedtime form used for unease rather than comfort. Its exact original recording is not clearly documented, so it is best understood as a soundboard meme rather than a line from a known film, song, or show. On short-form edits it spread because the repeated be-be-be hook is easy to recognise, easy to loop, and instantly signals that something innocent is about to turn creepy, keeping it useful for Halloween posts and dark comedy.
