    Well, I'll put it this way: if more than about 0.05% here knew what it meant, at least in some circles, I'd delete it as a forum policy violation!

    Okay now you've got me curious. Since I can no longer ask my grandfather about how that term came about, maybe you can email me the origination of the word. I promise I am way over 21 years of age
