I don't think it's a known term; it seems something GP created. As for how it works, the concept is simple: if the user wants to do the wrong or potentially insecure thing, just don't let them, period. That's the brick wall.
I'm of two minds about this personally. On the one hand, I appreciate the argument that the only thing that can prevent businesses from doing something bad, stupid or abusive is if it's legally, physically or by design impossible. On the other hand, as a pro user, I do appreciate the ability to override software when it mistakenly tries to prevent me from doing something.
