Fanbrat

Fanbrats are young, immature fans of any series. They are usually preteens, although not all young fans are considered fanbrats. Fanbrats are most commonly found in any fandom aimed at their demographic, such as Disney Channel shows, but can also be commonly found in anime fandoms. They tend to try to make up for their lack of life experience by behaving as obnoxiously as possible. They are the fandom equivalent of 'n00bs'.
