Meaning

Literally, "What is your favorite thing?" It’s a casual way to ask someone about the thing they like most, whether it’s a hobby, a food, a movie, or any other personal preference.

🎯

When to use

Use this phrase in informal settings—among friends, classmates, or on social media. It’s too colloquial for a formal interview or a business meeting, where you’d opt for "Quel est votre/ton truc préféré ?"
