Professional Amateur Pinball Association. I never understand the professional amateur bit. Is it meant to be tongue in cheek? Like we saying these are professional amateurs? Or is it meant to be like professional and amateur? Or is it saying that this is a professional organisation for amateur players?
It is an interesting question. There are really zero professional pinball players. Even the best in the world like Keith, Bowen, Zach, etc. do not earn a living from playing pinball, but have regular day jobs just like everyone else.
