Stupid question? My father and friend also know of the game and we're all not quite sure. I say "Nex - long u - iz( like is)" and my friend says "Nex - uz( like us)". We both say "Nex" similiar to "next".
I don't think its so much the "Nex" part as it is the "xuiz" part. I hope the way I described them weren't too confusing.
