The newest extreme sport where an individual proceeds to lie down, straight as a plank, face down, on a car a bench, etc.. and then have your photo taken in that position, and then put the picture on the world wide web.
George: Dude you won't plank on Jake's car.
Matt: I just did, now take a picture!
George: That's going on facebook, your planking the fuck out of his car!
