When one proceeds to lie flat on a dangerous/unusual surface, with their hands by their sides. A photo is then taken of the planker, and posted online. It is a competition to plank in the most unusual/dangerous place. People have died planking - yet it is still an internet craze. Its fucking stupid.

An extremely painful excersice in which one puts their elbows and toes on the ground and straightens their backs. aka Bows and Toes.

The internet craze that is sweeping the nation. Planking is for people who travel, are not athletic in any way, and who want to be noticed on the internet. It is the most disgraceful trend humanity has ever allowed themselves to do.

The stupidest fucking act ever where you lay on your stomach with your hands at your sides and stretch your fingers and feet downward and then post a picture of it on facebook. Many people choose to do this across a building, car roof, the ground, on another person, or on an animal.
