Fangirls
Obnoxious female fanatics. These obsessive and insufferable bitches will latch onto something for superficial and often stupid reasons and, much like leeches, will kill it slowly until it is uncool. They are easily spotted by their over-zealous dedication for a subject of pop-culture, self-described "nerdiness" and stupid t-shirts. Current victims of fangirl audiences are shows such as Doctor Who, Sherlock and Supernatural but they will soon will draw their attention to Game of Thrones or The Walking Dead
Fangirls are what killed Doctor Who.
