Bunko?

I was wandering about shopping options in Northern Nevada recently and found The Purple Avocado's site. They mentioned Bunko. Huh? I thought. What is Bunko? I found Helen Ginger's site that describes Bunko as being a dice game and a social event where people get together and cook and play once a month. Besides Bunko night recipe ideas, she has tons of writing resource links as well. Sounds kind of interesting. I don't know any Bunko people though.
