The phrase is Spanish for banned by Bobineitor, and online it works less as a real moderation notice and more as a running joke about sudden, over-the-top punishment. Short voice lines like this spread through group chats, livestream soundboards and short video edits because they can be reused in almost any context where someone messes up. Its appeal is the contrast between the formal idea of a ban and the trivial reason it is usually played for, which keeps it useful as a light, recurring reaction sound.
