What is the name of this movie?
I watched this movie a while ago the only parts I remember are that one of the guys is arguing with one of the other ones saying that if you decapitated then you can see your headless body for a few seconds before you die. Then later on he gets decapitated and we see his head looking back at his body and smiling. And the other part I remember is the killer carves words into someone's stomach or back I can't remember which one. I think the group of people were in an RV or something similar.
