Dead Whaling started in San Antonio, Texas, and has been compared to a spastic version of Planking or The Worm. To successfully do the Dead Whale, one must lay down on their stomach with their hands by their sides and begin a series of spastic seizure-like motions using the chest to gain lift.
Concerned Citizen: "OMG! Is that boy having a seizure!?"
Person Filming: "No you moron, he's doing the Dead Whale!"
