The phrase comes from Palmashow, the French comedy duo whose short, exaggerated sketches have long been quoted and clipped by French-speaking audiences online. Attention, nouvelle regle works as a self-contained catchphrase because it sounds like an official announcement while remaining deliberately over-the-top. Soundboard users have kept it alive as a quick way to flag a change of rules in games, challenges and parody videos, where its brevity makes it easy to drop into edits without slowing the pace.
