Acquired Situational Narcissism

A common trope among High School stories; a character gets his 15 minutes of fame or goes from Rags to Riches and lets it go to his head. The character will sometimes ignore old friends in favor of a new, "cooler" crowd, and almost always turns into a Jerkass egotist overnight. Usually, the Reset Button is pushed by the end of the episode, followed by An Aesop that Celebrity Is Overrated. Usually happens to ambitious characters, much to their chagrin, and usually as a result of the Popularity Cycle (whether because the person who decides what's in or out is on top, or because people are fickle). A form of Compressed Vice. Compare In with the In Crowd, Lonely at the Top, Drunk with Power, Nouveau Riche. Disability as an Excuse for Jerkassery and Bridezilla are Sub Tropes. Contrast Heroic Self-Deprecation, where instead of letting their pride get to their head, they refuse to believe they have achieved anything significant and still don't believe they are of any use. Named for a real personality disorder shown to affect people who become famous, making this a case of Truth in Television. Examples of that can be found in any of the more down-market newspapers.
