Nov. 7, 2013—Are you allowed to come up with new words? I think it's almost legitimate. Do you remember the Tebowing movement, the planking craze, or the milking silliness on YouTube? I'm calling it now: treeking started here. If you were wondering about the etymology of "treeking," the words "tree" and "freaking" were combined one day in the fall at Vanderbilt to describe the state of a particular student. So treeking is exactly that: freaking out about trees.
