The terms Hyzer and Anhyzer were coined by H.R. "Fling" Hyzer to describe the angle of release of a Frisbee. A disc enthusiast active in the 60s and 70s, Hyzer was known in his day as the Father of the "Flying Flutterball".
I always had the theory that Anhyzer came from Anheuser-Busch beer. I'm sure there was plenty of it on the courses back in the day. Even if HR "Fling" Hyzer is a real person, it is a great coincidence.
