I've been reading and reading and biting my tongue but I have to cave in now and ask. WHAT is it? I'm too old, too open minded (we'll leave it at that) and the consistent mention of this thing has finally got me bringing way too many things to mind. Save me. What is it? What's it for? How's it work? Got a picture? Oh and where are you all getting the good smilies???? Please watch your language. This is a family friendly board.
