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—
Fangirl 1: Shhhhh....
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 person whom is dedicated to a certain idol. This person has no life, and is okay with it. They usually spend their time on Twitter, Tumblr, Instagram, and/or facebook fangirling about their idol. They are also a part of a fandom. It is extremely addicting and needs a warning label.

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.
