Greeting: "Fun and games!" as in "It's time for fun and games!" or "Let's have fun and games!"

Maybe the person who said it doesn't know what they meant. If you ask them then you will know what they meant when they said it.

Games are fun and you heard it at the end of a game, so it doesn't seem mysterious. It could be as much a goodbye as a hello, the way Aloha is.

And on the other side of the coin, the saying (American only?) "Life is not all fun and games."
