What does "Rogor xar" mean?

Gamarjoba!
I am just beginning to learn the Georgian alphabet, but I have been looking abound in some message boards in Georgian, which use the Roman letters. I notice this expression (rogor xar) a lot. What does it mean? Is it something like "how are you?" or "what's up?"?

If italki supports the script, can you please write it in the Georgian alphabet?

Thank you!
