One who is committed to a specific subject in a
genre of popular culture such as comics, videogames, movies, ect.. in which they
will defend the subject, devoid of any proper constructed
criticism.
A fanboy may defend the new Star Wars movies, believing them to actually be
good, despite their obvious lack of quality and intelligence when comparing them to the original trilogy. In a recent example, Harry Knowles (of aintitcoolnews.com) in 2002 claimed that Star Wars Episode II: Attack of the Clones was the best Star Wars movie to date. Did he really mean that Attack of the Clones was better than The Empire Strikes Back (agreed among many to be the best in the series)? Was Harry's statement made just so he could claim he had the minority
opinion? Perhaps not, but his devotion to the Star Wars movies at the
time influenced his statement a great deal, and further implemented his way of thinking. In the end, fanboys, such as Harry Knowles,
will always believe that the next installment in a franchise
will be better than its predecessor; thus no matter how
bad something is a fanboy
will always like it.
