Females often between the ages of 11-19, obsessed with book series, television programs and/or celebrities. They can be found at local bookstores, arms filled with books they will probably read at a much later time. 78% of the fangirl population stock up on books in case they need to go into hibernation, a form in which they stay in bed all day obsessing over fictional characters. Fangirls are usually harmless, unless approached when reading/watching an important event (which is not recommended). They are mostly seen wearing comfortable clothes, next to no make up, carrying a miming of two books and, sometimes, with earphones in.

The armpit women of generation Z (and Y if unemployed). They spend countless hours trying to get noticed by their idol and comment with irritating jargon under their idol's uploads. They are cult-like women who form group "fandoms" and resort to an idiocracy known as "shipping" which is sexually or creepily imaging their idol dating or having sex with an other heart-throb idol. They are found watching and drooling at profiles, pictures, and YouTube uploads of popular attractive teens and twenty-somethings. They are rapidly expanding and must be exterminated at once.
For further research on fangirls, get on YouTube, Tumblr, or Instagram for that matter...

Fangirls, on the internet, are people who are obsessed with or in love with a fictional character. Most are bad but some are good. (They'll often attack you if you like the same character....) Don't attack the good ones. Duh.
