au revoir means good bye ;)
No it means 'see you later'. Voir is seeing and re means again.
It means both xD
The common usage is for "good bye". But it does primarily mean "see you again"
We Frenchies tell "au revoir" even if we are not going to see the person again and this even though we have "Adieu" that means "good bye we will never meet again" but is barely used except in classical littérature I guess...

Hey hey what does "au revoir" means?
Let me guess "let we be reunite again"?
