Main character of a book called The Catcher in the Rye. Most American kids end up having to read it at some point during high school. Main character is a teenager who gets in trouble at school and runs away to New York City and has a series of adventures and misadventures. Probably has untreated depression, but it was set just post World War II, so the time period wasn't great for mental health issues. The main thing about the character is that he's pretentious as hell. Most people don't particularly end up liking Holden when they read the book.
