A girl with an obsession of something. Can be a celebrity, anime, a band e.t.c. popular obsessions are Orlando Bloom, Elijah Wood, Inuyashamashywhaever, and Good Charlotte. Most of them do have lives outside of their crush apart from the odd scary one. They can produce quite good fanart and fanfiction. Many are good-looking and thin (e.g. many of my friends). Many are also nice people who are capable of answering a question with 'squee' or 'OHMYSEXGAWD'. I am a fangirl and proud.

An overly obsessive female. When referring to anime, one is usually obsessed with bishounens such as Inuyasha, Sasuke, or anyone from Saiyuki. The typical fangirl cry is, "SQUEE!!!". Fangirls are also equivalent of stalkers and many are shot on the spot when seen.

A female fan of an actor and/or fictional character. Usually between the ages of 12-14. Is known to utter high-pitched sounds whenever the object of their obsession's name is mentioned. Claims that, "IM reelly gona marry him cuz we R ment 2 b!!!!!!!11111!!!!!!@#$347903458134!@!@!" Uses excessive amounts of punctuation. This condition is usually just a phase and doesn't generally last extremely long. However, in the more severe cases the fangirl can go on in her fangirlyness for years on end.

Someone who gets easily obsessed with things they view, read or are involved in. They belong to things called 'fandoms' and generally scream and cry over characters that may be fictional, or band members and actors, singers, authors or bands.
Person A: Wow, she's such a fangirl!
Person B: Yeah, she screamed in excitement and then burst into tears when their new book came out...
