What does Au-revoir ne trou mean?

The phrase "Au revoir ne trou" is not a standard French expression and doesn't have a clear meaning. It seems like a possible misspelling or a made-up phrase.

Here's why:

* "Au revoir" means "goodbye" in French.

* "Ne trou" doesn't exist as a word in French. It might be a misspelling of "ne trouve," which means "doesn't find."

If you were trying to say "goodbye, I don't find," the correct French phrase would be "Au revoir, je ne trouve pas".

It's important to be careful with French phrases, as there are many variations and subtle nuances that can change the meaning significantly.
