To lie face down with an emotionless face, arms to the side, in a rigid manner. Can be done by anyone on anything to make an impressive picture. It is proper to have a picture taken of oneself planking and post it on Facebook. Originated by British Rugby player David "Wolfman" Williams
Jim- What is that idiot doing laying on the park bench face down looking like a zombie
