A girl obsessed with an actor, book, tv series, etc. Keep in mind the male counterpart the “fanboy” also exists, but fandoms are female predominated. Girls like this will kill you and/or severely injure you if you utter one ill word of their otp, fandom, favorite actor, etc. Mind your tongue around them.
Fangirl 1: What is your OTP?
Fangirl 2: Oh definitely Destiel, Pipabeth, and Sabriel
Non-Fandom Member: But you can't have more—
Fangirl 2: Shhhhh....
Non-fandom member: But it's called a One True—

A young female, generally between the ages of 12 and 19, that is obsessed witha pacticular fictional character and the actor who plays him/her. Avoid fangirls at all costs especially in large groups as they tend to swarm and if you are unlucky enough to catch them near their object of admiration, cover your ears and run. They have a batlike shriek that can be heard for miles. Also known as stalker in training

A girl who will do anything to see her obsession. Fangirls mainly of boy bands,anime,actors, and or fictional characters. Usually have more knowledge on them then they're own family. WILL CRY THERE EYES OUT AT THE CHANCE TO MEET THE OBSESSION. These girls belong to fandoms. never insult a girl on her fandom or else. (This is a warning.)

1. Usually a girl who pretends to have absolutely no self esteem whatsoever in an attempt to get the attention of a celebrity. Either they're pretending or they really don't have any self esteem. These people have an unhealthy obsession and will stop at nothing to get attention. These people have no lives; their celebrity obsession is their priority/occupation/etc... (figuratively, that was a joke kinda)
2. A girl who has a firm grasp on her emotional investments and can laugh and joke about her infatuation with a celebrity. These people have a healthy fascination, are able to lead normal lives, and will probably be better off in this world...

A fangirl is like a groupie, only underage or extremely unattractive. Groupies follow the band/artist/celebrity around and sleep with them. Often, fangirls say how much they would LOVE to sleep with the member and basically obsess over the band and/or musician it is normal to find posters and pictures of a certain celeb all over their walls and as their desktop background. They also make other, more normal fans look bad. How to eliminate a fangirl: garlic and sufficient sunlight work.
