When an individual person lays down, in a straight, face first position in an unusual place, whilst someone else takes a picture of this. These pictures are often used as profile pictures. Very popular in Australia, although frowned upon because of an unfortunate death involving a multi-story apartment and a window ledge.

Lying flat and straight, face down on as small a surface as possible. The weirder or more dangerous the location the better.

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

The act of lying face down, palms flat against the sides, and feet together pointing at the floor. The event must take place in an odd location and shared via the internet to be considered an official "plank." It is allegedly dangerous.
