That scene came out of a soft porn japanese movie back in 1995.
She tempuraed her hand and deep fried it then took a bite out of it
before she sliced off her pu$$y lips than proceeded to eat her
eyeball. 
Its some horror show about a guy who
comes up with a super painkiller, the more pain you feel, the
better you feel. That gal in the video is just one of the 3
victims, one of them pierced herself to death. The last one, had
sex with him, strangely with no ill effects.
