The line comes from La Classe américaine, a 1993 French TV film by Michel Hazanavicius and Dominique Mézerette. The movie is a détournement: footage of American films redubbed in French to form an absurd new story. Several of its rewritten lines entered French pop culture, and this one became a staple of online humour thanks to its exaggerated anger. It spread through forums, parody videos and soundboards, and is still used today as a punchline whenever someone wants a ridiculously dramatic French swear.
