Professional Plankster. I came, I saw, I planked. To plank. To lay horizontally in a strange or unusual place. To plank you must lay horizontally straighten your body and point your fingers and toes down (towards your feet), then you must name your "plank" and post a picture of the creator (of the plank) performing the pose on Facebook. Planking is a great pastime for people who get bored easily and have friends willing to take pictures of them looking like retards. Public planking is more adventurous and is harder to pull off especially on things like: cop cars, public toilets, and in the middle of six way highways. Planking can also be dangerous if performed: in places of frequent use, the tops of tall buildings and placed frequented by pedophiles and rapists.
