Little is documented about where this exact recording first came from, so its life has mostly played out as a shareable soundboard and short form video clip. Users circulate it under variations of join the flock and baby lalala, using the shouted invite as a punchline for arrivals, recruitment jokes and fandom in jokes. Its appeal comes from that switch from loud confidence to nonsense singing, which works without explanation in edits, streams and group chats, and keeps it in rotation as a lighthearted entrance meme.
