The hosts detail Slenderman's origins in 2009 on Something Awful, where Eric Knudsen's faceless figure was expanded through community collaboration, gaining traits like targeting children and appearing in photos before tragedies. The found-footage series Marble Hornets further popularized the character, blurring fiction and reality. Slenderman is described as a tall, faceless figure in a black suit who stalks vulnerable people, causing paranoia and 'Slendersickness,' and interacts with technology by appearing in recordings. The discussion then shifts to the Waukesha stabbing, where two 12-year-old girls, Morgan Geyser and Anissa Weier, stabbed their friend 19 times to appease Slenderman. The hosts debate the girls' mental state, the insanity plea, and parental responsibility, emphasizing that such cases involve complex factors beyond the fiction itself. The episode concludes by framing Slenderman as a prime example of digital-born folklore, reflecting modern fears through collaborative, decentralized creation.
