Planking or the lying down game is an activity consisting of lying face down in an unusual or incongruous location. The hands must touch the sides of the body and having a photograph of the participant taken and posted on the internet is an integral part of the game. Players compete to find the most unusual and original location in which to play. The term planking is described as the practice of lying down flat with arms to the side, to mimic a wooden plank.
Many participants of planking since 2011 have photographed the activity on unusual locations such as atop poles, roofs and vehicles, while some "plankers" engage in the activity by planking only their upper body and feet while leaving the back suspended.
