Fangirls are a group of people (usually female) that obsess over things like celebrities, youtubers, actors, bands, or TV shows, and make a point of letting people know. They are known to want two people to be in a relationship. This action is commonly known as shipping. One may even ship themselves with a person or character.

They usually band together in groups when in a public setting, and it is rare to see a lone fangirl, well, fangirl-ing, in public. Their obsession can lead to irregular body language and facial expressions, suck as bouncing up and down, waving their hands around frantically, glomping, and in special cases, threats of violence. Although, thankfully, no fangirl has actually harmed a person worthy of a hospital stay.

Some place to find fangirls are at conventions like Comic Con, or on websites such as Wattpad, FanFiction.net, or ArchiveOfOurOwn.

Not all fangirls are as crazed as they are usually stereotyped as, though. Others just have it as a subtle hobby/part time sort of thing, while others see it as their career (i.e. wHo NeEds a jOb WhEn I hAvE FaNfIcTiOn).

I will tell you this though, only fangirls truly get each other...

Wafflebutter69, also known as Nina. She constantly fangirls over benatar from your favorite martian. Like more than half of her drawings are of him and she always says “weird” things about him so yeah, Nina is the definition of a fangirl.
Person 1: do you know wafflebutter69?
Person 2: oh yeah, she drew herself banging benatar. What a fangirl.
