Sacrebleu !

Le mot du jour : “Sacrebleu !” (literally Holy blue)

Swearing words that no French people ever use in real life 😀
This expression started with Henri IV, king of France at the end of the XVI century, and well known for swearing a lot, using the sacrilege expression “sacredieu” (holy god). His religious advisors thought better for him to use something more respectful, and created the now well known “sacrebleu”.
Even if you can find it in almost every article about France here, in reality people would be very surprised to hear someone use it.
If you don’t want to seem too outdated, go with “La vache !” (une vache is a cow) 😄
