A stereotypical french curse that is actually never used by real french people. Same as the mustache and the beret - something only non-french people think is typical of the French.
Non-French Guy trying to be French: Sacré bleu! I hev left my béret and stripy chemise in zee Café.
Real French Guy: *rolls eyes*
x: Sacre bleu! The cat has washed the dishes!
y: I knew she would if I asked her enough times.
