Boyband fangirls are pretty typical. Just type in "fangirls crying" to any search engine and you'll see a massive pile of confused little brains exploding with emotion and pubescent frustration.
This video goes through a list of various things I hate about fangirls, specifically those who are fans of bands created by corporations just to take advantage of gullible teenage girls who are more scrambled brain chemicals than human. The instability, the insanity and blind obsession, it deserves a 10 things response.
This is the reality of the majority of 1d, 5sos, Justin Bieber and various other fangirls.
