Broek uit translates from Dutch as pants off, and the repeated chant has circulated online as a short soundboard clip rather than a full song. Its file metadata tags the underlying audio as El Ninjo by electronic producer William Orbit, which explains the polished dance backing beneath the shouting. At just over six seconds, the clip fits the format of shareable meme audio that spreads through group chats and short edits. Dutch listeners recognise the phrase instantly, while others use it purely for its loud, looping energy and obvious comic timing.
