"Didn't some Teutonic tribes use it?"
I think you are right. I just call all bush-worshippers "Druids" out of laziness.
In fairness, I think Druids threw vigins in peat bogs, whilst the Franks tied them to the Tanenbaums and let them die of exposure. (Or somesuch -- I don't really care.)
Remember this when decorating the tree. Merry Christmas!
HEHEHEH, is that how that fairy got stuck on the top of the tree?
Whoo boy, now I've gone and done it.
