what does FAF mean?

It's a sacred tongue, that with decades of cultural context built within the fabrics of the script. You have no need for such knowledge, Zixvir.

well google's opinion is:

I don't agree.

one possible thing that is could stand for is:

Friends and Fighters.

But it is also possible that it is a word entirely on it's own that stands for good friendship.
