People that call it frisbee golf probably came up with the term "field ace".

I purposefully call them frisbees just to get under the skin of people that it bothers. I guarantee that those same guys use kleenex instead of tissue paper, and band-aids instead of bandages, so the fact that they get so up-in-arms over their beloved discs is just funny to me. Guess what? Before I knew what disc golf was, every single flying disc I touched was called a frisbee. If you talk about "disc golf" around anyone who doesn't know what it is, they have a really confused look when you first mention it. But if you say "frisbee golf" instead, they instantly know what you are talking about, even if they have never done it before. Sure, around other people who are really into it, I speak with normal disc golf terminology, but around most people it just doesn't make sense to. You end up spending most of the conversation talking about what the different terms you use mean, versus actually talking about the game.

Also guess what, yes, frisbees were a trademarked product made by wham-o. Know what else? There is an entire sport that is easily as popular as disc golf that uses nothing but frisbees, calls them frisbees, and they certainly don't get their feathers ruffled over the fact that they aren't throwing the actual trademarked, wham-o discs. It's called Ultimate FRISBEE. Not Ultimate Disc, or Ultimate Ultrastar. Mainly because if I saw an ad for something called Ultimate ultrastar, while I would be pretty interested based on the name alone, I would have no idea what the game was about. If you say frisbee, everyone knows what you are talking about.

To me, getting all sandy because someone calls it a frisbee just goes to show me that a person is rather pretentious and stuck up about a sport/game that is supposedly so open and friendly to everyone.
