relating to the term "black book," being black listed means to be just another girl that a guy cheated on his girlfriend with. The guy is usually a charmer who tries to convince each girl that she is different and special. Sometimes he may even mean it and dump his girlfriend, but they'll always get back together. He can't be alone, but he also doesn't like commitment, as so the Black List grows and grows. The guys most common quotes are usually "It's different this time" or "I really do care"
girl one: that freshman hooked up with Adam. He convinced her he was going to actually leave his girlfriend.
girl two: but she really just got black listed...
