Cava Quoi

"Cava quoi!"

Not the answer a typical Belgian will give you when asked how it's going.

But the answer someone gives the result of something is better than expected.

Example:
- How much are these maft sweaters actually?
- Only 68 euros.
- Oh, cava quoi!

Less than expected.

A very reasonable price considering how unbelievably awesome you're going to look, wearing it.
