Robination

An idea or illusion that is being used to convince one of something other than the reality. Most often used in a context to make someone believe they are more or less relevant than is actually the case; the act of trying to portray that oneself is more interesting and deserving of something despite a lack of actual personality or character. Can be applied in a broader scale to convince a group or population of people that an Individual is not to be trusted or respected to distract from their own negative attributes.
