1. Est-ce que je te demande si ta grand-mère fait du vélo? | Mind your own damn business
Translates literally as, “Do I ask you if your grandma bikes?” This is a rather funny (though not for the person receiving the insult) and sarcastic way to tell someone to get lost.
Example:
-
- A: Is your divorce procedure with Ginny coming along, John?
-
- B:
Est-ce que je te demande si ta grand-mère fait du vélo?
