aka frisbees
If I may though, I'd like to point out something. The reason why people who do disc sports don't like to refer to the disc as "Frisbee" is mainly because "Frisbee" is a registered trademark by Wham-o. I'd say call it whatever you want, but for example, you wouldn't want to wrongly use "Frisbee" (like in a company name) and get in trouble with Wham-o or something.
Also there's a lot of different discs, simply using "Frisbee" for all of them could cause some confusion, I guess.
