Planking

Planking is an adjective that, when applied to any living object, will make it fall facedown, and not move at all.

Trivia

 * This adjective is based on the real life internet meme where people would lie facedown, stiffened up, in the most awkward, amazing, or physics-defying positions possible, without moving at all.
 * Some living objects will simple appear as if the adjective "dead" were applied to them.
