I did a search but couldnt find it
could you please help in locating a movie
i think it was like 3 or 4 parts
was a couple of cheerleaders fighting at a lake they would fight then stop then fight some more then stop
alot of people were standing around watching and cheering them on while fighting and ripping off each others tops
looked like collage aged girls
looked real to me not staged

looked to be at a park / lake
