I remember watching this movie on netflix.  Two guys and three girls met in a bar and drank.  They met a guy at the bar and the guy went camping with them.  Don’t remember much in the middle.  A killer has a house in the woods…probably dragged one person to his house and started killing him/her.  The friends went to the house and ttry to help the friend.  For some reason I keep thinking that the mv title is “Pest” “Piest” or something short like that.
