Definitions for "Fangirl"
A female fan who is overly obsessed with a fictional male character, voice actor, J-rocker, etc. Similar to the breed of fanboy; masters/creators of the Glomp, Tackle Glomp and 'Fangirl Squeal'.
in animé and other fandoms, a female fan obsessed with her favourite series/character e.t.c. to the point where it is considered unhealthy by most, even otaku. Many people consider it derogatory, but some of us... uh, I mean some people, call themselves fangirls with pride. The scariest breed by far is the yaoi fangirl, who's obsessed with bishounen and writing fanfics based around the after-dark antics of Sephiroth and Vincent. Tomoyo from Card Captor Sakura is probably the über-fangirl. Also comes in the male form fanboy.
a female, usually between the ages of ten and twenty, who is a fanatic about any series, game or person (typically something or someone popular)
