Mabuhay!
If you've been to the Philippines, especially if you flew on Philippine Airlines, I'm sure you've been greeted "Mabuhay!" at least once. The literal translation is live (like long live the queen and not like a live concert). It is a pretty good greeting. And some sound advice, too.
BUT...
Filipinos do not greet each other "mabuhay". Since English is one of our national languages, we usually greet each other with a casual "hi!" or a slight less casual "hello". Often this will be followed by a one word question "musta?"
