Osoroshi byosha 

Osoroshi byosha is an art style in japanese pop culture. Osoroshi byosha translates to "horrifying depiction" in japanese. An Osoroshi byosha's appearance is quite unsettling, having a humanoid shaped head, two blank staring eyes, and a thin line for a mouth. The creation of Osoroshi byosha started with a small internet joke but then started to expand, many japanese audiences describes these depictions as "So horrifying that i laugh".
