A stupid "sport" invented by Australians, it involves lying on your stomach while holding a plank form. This is often attempted in dangerous places to prove that this lame sport is not so lame. A few people have died, yet people still go crazy for this "sport".
Kangaroo Australian: Hey lets go planking on dangerous things.
Koala Australian: Planking? You mean that stupid "sport" that Australians do where they lie on their stomachs and lay on weird things?
Kangaroo Australian: Yes, that "sport"

Planking is the art of lying down with a stiff body on any random object. Planking originated in Australia and has now become popular. Planking is an evolution of parkour, it is for people who cannot do parkour and want to look "cool" by taking pictures of themselves planking. Planking is pointless, if you want do something useful, learn parkour.

To purposely lie face down with hands and feet together. Usually done in a weird location such as on stairs, vending machines, or cars. The point of this act is to photograph it and place it on FaceBook where it will be marveled at and or laughed at.
