Fanboy
Fanboy is a derogatory term used to describe someone who is utterly devoted to a hobby or a subject, to the point where it becomes an obsession. "Fanboys" are often experts on minor details regarding their hobbies, and they take these details extremely seriously. The stereotypical image often associated with Star Trek fans (or Trekkies) can be used to describe a fanboy: a person with little or no social life outside the circle of fans he or she associates with.
An alternate, more recent example of the "fanboy" is someone whose enthusiasms are shallow but broad, being directed at a whole art-form, activity, or genre (e.g. science fiction films and telvision shows) rather than one particular examplar (e.g. Star Trek). These sorts of "fanboys" stereotypically show an almost sycophantic devotion to the creators and principals behind a work they are currently entralled by, but will quickly move their attention elsewhere once something better or even only newer comes along. A good example of this is Harry Knowles and his associates at Ain't It Cool News, whose particular focus is on movies in the action, fantasy, adventure and superhero genres.
Because of its negative connotations, the term "fanboy" is generally seen as insulting to those who are familiar with its usage, even within the subculture of fandom.
