An Orwellian state that watches your every action and tracks everything without the knowledge of the governed. Think a Two Way Mirror. First coined on the XKCD forums.
With all of the Big Brother-esque surveillance currently in place that has been deemed Classified for "National Security Reasons" The USA is a Half-Mirror Society just begging for revolution.

Someone becomes a "One Way Mirror" when they are attempting to form a relationship with someone, but is the only one individual is interested in bonding. This leads to very one-sided relationships where one person knows a lot about the other, but it can't be said vice-versa.
Person 1 :Jack is being a total One Way Mirror, he won't leave me alone & keeps asking me all these questions. He knows so much about me, but I don't even know what classes he's taking.
Person 2: What a creep, can't he take a hint?
