At its most basic sense, to "tree" is the action of spending
prolonged periods of time in a single spot. With this, the goal is often to adopt the
lifestyle/lifecycle of a tree, which just consists of sitting in one spot its whole life and dying. Why, this term is quite
subjective, as spots can range from someone living in the same city their whole life to being penned in one small room for days on end.
Man 1: "Come one, Jimmy, why won't you join us?"
Man 2: "I think Jimmy is highly depressed; he hasn't even left his house in weeks, let alone
engaged in social interactions."
Jimmy: "I'm not depressed, I'm just treeing."
(little do they know, Treeing is often a sign of either a sense of fulfillment and lifelong
satisfaction or deep sorrow and lack of motivation)
