Someone who is
obsessed with a particular
tv show,
book series,
video game, or other mainstream
entertainment -- typically of the
sci-fi/
fantasy genre -- to the point where they will
collect every
marketable product available
related to the SBG (show/book/game) which they can
afford. They will
defend their obsession
vigorously, even
violently, against
fans of other SBG's, or even against fans of the same SBG who
ask them to even
consider the
remote possibility that the SBG has any kind of
flaw whatsoever. Frequently seen in
chat rooms or
Internet message boards posting in
incomplete sentences and
swearing a lot.
Fangirls have been theorized to exist, but have never been seen in the wild.
