The most beast no faces CreepyPasta there is. Tall as fuck, and with arms and tenticles that can tear you to shreds he is quite a treat. He makes electronic devises go crazy when he is close to them. And the only thing that sucks is that his weakness is 8 pieces of paper

Guy 2: Run nigga run!! Slenderman is here!!!

A Slenderman is an abnormally long yet thin penis. In order for a penis to qualify as a Slenderman, it must be capable of being coiled in a circle twice while flaccid.
1- Daniel has a Slenderman, so I bet he's really good at docking

2- I do say, I just saw the most unsettling Slenderman in the locker room.
