As a kid, I learned from a song that the French word "connard" meant "a**hole."
One time, when I was in school, I called someone a "connard" and the teacher heard.
The teacher sent me to detention, which led me to believe that all French words were swears.
And the ironic part was, it was my SPANISH teacher who heard and sent me to detention.
A childhood belief about swearing
