Certainly not a common word in my world, TRex, and nor many others including this game if the count is anything to go by.
The next least played common words were played nearly twice as much, there were a dozen or so other uncommon words played more, and I can honestly say I have never seen it used, nor heard it used during my lifetime.
Oh well, live and learn.
As for tourney, I have heard of it, but am not surprised that it’s regional it’s raised questions. It always does, whatever Regions words come up.
