For example, we could be the PPC - a collection of people who strive to make use of a satirical sense of humour to define what is 'Acceptable' and what isn't in the world of Fanfiction writing. To do this, we make stories that parody the cliches of writing, using a pre-existing text as our basis.

Or, otherwise, the PPC is an organisation of sentient beings who are controlled to take a stand against the stock character of the 'Mary Sue'

That's my definition anyways.
