About Slender Man (a.k.a Slenderman) is a mythical creature often depicted as a tall, thin figure wearing a black suit and a blank face. According to the legend, he can stretch or shorten his arms at will and has tentacle-like appendages protruding from his back. Depending on the interpretations of the myth, the creature can cause memory loss, insomnia, paranoia, coughing fits (nicknamed “slendersickness”), photograph/video distortions and can teleport at will. The urban legend has inspired fan arts, fictional creepypastas and a mockumentary series in the style of the 1999 indie horror film Blair Witch Project.
Origin On June 8th, 2009, a “’paranormal pictures” photoshop contest was launched on the Something Awful (SA) Forums. The contest required participants to turn ordinary photographs into creepy-looking images through digital manipulation and then pass them on as authentic photographs on a number of paranormal forums. Something Awful users soon began sharing their faux-paranormal creations with layered images of ghosts and other anomalies, usually accompanied by a fabricated witness account to make them more convincing. On June 10th, SA user Victor Surge posted two black and white photographs of unnamed children with a short description of “Slender Man” as a mysterious creature who stalked children.
