These tests are designed to exclude others from the discourse - just as the word discourse is itself designed to do. These words are intended to say to people: this is a group thing. If you don't understand what we're talking about, you're not a member of the group. So, if you call this place the Canny Man's it shows that you belong, that you know what's what in Edinburgh. And that, you know, is what everybody wants, underneath. We want to belong.
