Alright, I can't remember the name of this movie and thought maybe someone here does. I remember watching parts of this movie on the movie network late at night like 8 years ago. Basically all I remember was there was a group of people in a facility or something and they're the only ones there and they have guns and constantly have sex, and this skinny guy gets his head pulled off by one of the guys and his head is smiling. Also somebody walks into the room of this Asian girl and on the screen is a GIF of her cumming and I'm pretty sure this blonde guy kills his Asian girlfriend then tries to kill the other two a girl and a guy and he turns all hulk-like and gets all red and huge. I remember it being only centered around this 5 or so people and no one else is in the movie.
I'm pretty sure the blond guy at the end blows up.
Sounds like the extremely awful "Teenage Caveman" (2002).
