The term creepypasta is a neologism referring to a specific form of copypasta designed to frighten the reader on internet forums. These short stories, copied and pasted by users who often remain anonymous, are typically left without citing the original source. Due to the generational nature of their transmission, the original source is probably not known. The modern equivalent of the urban legend, creepypasta is able to utilize viral, or memetic, transmission to reach a wider audience much more rapidly than it's word-of-mouth predecessor. The often-pasted "Dionaea House" gained enough moment to be sold to Warner Brothers. Creepypasta is found primarily in forums such as 4chan.org, 7chan.org, and somethingawful.com, though offshoot forums have now been developed solely for threads regaurding user short horror fiction, such as http://www.parachan.org/ .
