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.
Dude, did you see that guy lying on top of that 8 storey high pole?

Yeah man, he was planking.

Oh. Get a photo before he fell?
