How do you say "nothing happening"? Is it "Nan boule"?

I guess if you mean "not too good, not too bad".

A Haitian will definitely say: "Anyen non!" when they mean to say "nothing's happening" after you've asked them how they're doing.

Nothing's happening → anyen pa'p pase, pa gen anyen k'ap pase, anyen pa bouje

Ask me anything
