When French people want to say “elbow” they say “coude”. When they want to talk about someone’s bottom they say “cul”. In fact, they have a whole different language, called “French”.
The words “coude” and “cul” are almost indistinguishable when actually spoken by a French person.
I think what I’m trying to say is that when I’m in France, I don’t know my arse from my elbow.
