A form of dance used to show that you and/or your friends are having more than just a good time. To perform the dance, all one needs to do is simply put their arms infront of them (kind of like a zombie) and put your head down. Then kind of bob up and down and there you have it. Simple, yet amazing.
Example One:
Joe: Look at Ford on the stage! ...What is he doing?
Peter: Why, that's The Dead Tree! Ford must be having a great time.
Example Two:
Jimbo: Dude, I love this song!
Wallace: DO THE DEAD TREE!!!
