What is Spirit of the Game? Describe it, what does it mean to you?

In the 9th edition of the Official Rules of Ultimate (see below quote), the UPA (Ultimate Players Association) let’s the individual player define “Spirit of the Game.” To many Ultimate Fan-atics this is the core idea of “Spirit” the individuals ability to self-govern the game.

I find that the hardest part about describing SOTG is that it’s not something you can easly pin down with words, everyone describes it differently. Could the core idea behind SOTG be a respect for the individual and self-government? Do you agree? Am I glossing over too much? and of course my opinion is subject to change.

~~Most Ultimate players care deeply about Spirit of the Game. The organizational challenge for the UPA – the Players’ Association – then, is to foster an environment where the challenge does not become, “to see what I can get away with”. Rather than dictate what Spirit of the Game is or should be, it is up to each player to do so for him or herself within the context of the teams he or she plays with and against.~~
