Motus was a long-running French television word game in which two teams guessed words letter by letter, drawing balls that could help or hurt their progress. The boule noire, literally the black ball, became its most feared draw, a symbol of sudden bad luck that French audiences recognised immediately. Clips of the moment now circulate online as a shorthand reaction sound, especially in French-language edits, quiz parodies and fail compilations, because the sting needs no explanation for anyone who knows the show. Its appeal endures as a compact way to mark an unlucky turn.
