An idiotic fad in which kids lay flat across a surface with arms at sides, chin up and toes pointed. Although, half of them just lay across the surface.. Then post pictures of this act on social networking sites such as facebook, thinking it makes them cool.
John: "Ayeee, look at the kid planking on the feild goal post!"

Scott: "Dude, that's the stupidest thing i've ever seen. I hope he falls."
