That was by far one of the weirdest movies ever.
Two of the main what the fuck moments were:
One: The part where main chick beats her boyfriend/psychologist over the head with a gaint block of wood, then proceeds to crush his balls. Then after that he passes out she jerks him off until he ejaculates blood then drills a hole in his leg to put some weight thing there so he can't get away.

Two: Then later on in the movie she just randomly starts masturbating then cuts her clit off with a pair of scissors. I was like, seriously, what the fuck am I watching?
