then, out of no where, the guy stabs the girl with a tire iron killing her, still thinking she was already dead in the first place. the dead girl starts like haunting and killing everyone that was involved with the prank/murder. it was about this group of girls who play a sort of prank on some guy. this 'dead' girl is actually alive tho. thats the prank on the guy. does anyone know what movie this is?. the girls pretend that one of their girl friends is dead and they need to cut her up and throw away the peices of her body.a
