What does oo la mean in french?

"Oo la la" is not actually a French phrase, but rather a playful English imitation of how French people are stereotypically thought to speak.

It's often used to express:

* Surprise or excitement: "Oo la la, that's a beautiful dress!"

* Pleasure or enjoyment: "Oo la la, this food is delicious!"

* Desire or attraction: "Oo la la, you look so handsome tonight!"

However, while "oo la la" is understood by French speakers, it's not something they would say themselves.
