What does fais deaux mean in french?

"Fais deaux" is not a correct phrase in French. It seems like a misspelling of "fais deux," which means "do two" or "make two".

However, the phrase "fais deux" is not very common and is likely to be used only in specific contexts, such as:

* In a game or activity: "Fais deux pas en arrière" (Take two steps back).

* As a command: "Fais deux copies de ce document" (Make two copies of this document).

If you can provide more context, I might be able to give you a more accurate translation.
