Have you every played ultimate frisbee before?
Ultimate frisbee? Is that different from "regular" frisbee. No, I don't think I've played it before. Why don't you tell me more about it?
Yes, ultimate frisbee is quite different then regular frisbee. Although it is still played by using a disc, which you can actually use different types of discs that can be more difficult to handle.
Is it a different kind of disc, though? What makes it "ultimate"?
What makes it "ultimate" is that it is self officiating and that their are higher levels of competitions that you can attend. 
So it's competitive, unlike the frisbee game that kids or dogs play then. lol Actually, do kids play ultimate frisbee too? Are there competitions for kids too?
Even though it is a non contact sport, I wouldn't see kids playing ultimate frisbee due to the high levels of competition and the physical ability you need in order to play the game. 
You sound like a serious player of ultimate frisbee. When did you start playing and do you compete regularly?
