I've been perusing Scott Adams' Dilbert and the way of the Weasel over the weekend. It's really good. Right off the beginning, he is out to improve his definition of the world from the excellent The Dilbert Principle:

When I say "weasels" I'm sure you know what I mean. But that won't stop me from explaining it for a few hundred more pages because it's the sort of thoroughness that you expect from a member of the intelligencia, or innteligentia, or whatever

Weasel Definitions

Throughout this book I will concoct new phrases and definitions so that my ideas are revolutionary. As you know, nothing worth knowing can be explained with regular words.

Weasel Zone: There's a gigantic gray area between good moral behavior and outright felonious activities. I call that the Weasel Zone and it's where most of life happens.

[The Weasel Zone is] sometimes also known as Weaselville, Weaseltown, the Way of the Weasel, Weaselopolis, and Redmond.
