When you are sprinting on a treadmill and you fall and your face gets raped by the moving treadmill. If their is a wall behind the treadmill, you also get wall raped (look up if necessary) the treadmill shows no mercy in viciously raping your face and spiting you out behind it once it is done. if you notice a slight change in speed, stop immediately and call the Tread mill Rape hot line.
Bill says:"Dude, what happened to your face?"
Mark replies:"Oh, its nothing, just got Tread Mill Raped last night"
