The line comes from La Tour Montparnasse Infernale, a French comedy film released in 2001 starring Éric Judor and Ramzy Bedia as window cleaners caught up in a hostage crisis in the Montparnasse tower. In the excerpt, a character proudly calls himself a racaille de Changhai, using an old French spelling of Shanghai that explains the many search variants for the clip. Fans of the Éric et Ramzy comedies have kept the quote alive as a piece of quotable French humour, and short-form editors now reuse it whenever a scene needs an instantly recognisable, overconfident introduction.
