Intro. Jeff the Killer is a fictional character in the online horror fiction subgenre, creepypasta. He is depicted as a pale, man with long black hair and a Joker-esque grin carved into his face, known for his pre-murder catchphrase, “Go to sleep.” Jeff the Killer is one of the acclaimed horror Creepypasta legends equivalent to the popularity of Slender Man. Created by Sesseur, the Creepypasta centers on Jeffery Woods, the 13-year-old evil protagonist of the series who garners the epithet “Jeff the Killer” later in the storyline. Jeff later got his most distinctive trait, the Glasgow smile, that he had carved into his face with a knife. His build is commonly described as slim but fit at the same time and reaching a height of around 5 to 6 feet (1.5 to 1.8 m). During the struggle with Keith, a tub of bleach drenched Jeff, and Keith took this opportunity to set Jeff on fire by throwing his lighter at him.
