Noun. A form of basketball defense in which the defender mimics a tree. This is often accomplished by waving your hands majestically like a tree's branches in the wind. Occasionally the defender slaps gently at the ball in the opponent's hands. The goal of treefense is to prevent the opponent from scoring by making them laugh and miss their shot.
Bob could not stop Eston's drive to the hoop so he used treefense to win the game.
