A person who is mindful, rational, and able to analyze and make independent decisions and take independent actions not based on peer pressure, trends, fads, or superficialities. One who does not follow any particular crowd but is an equal-opportunity critic. A person with a high need for cognition (look it up). Unsheeps are the opposite of sheep. Their theme song is "What the world needs now is no more sheep, no sheep! It's the kind of human that there's just too many of . . ."
"Unsheep" derives from World of Warcraft's use of the term "sheep." No mage, including presidential mages can sheep the truly unsheep. They are unsheepable and protected from propaganda by their need to think.
