1. A treeplanter who consistently plants a lot more trees than anyone else.

2. A misguided young person who has been conned into generating a tremendous amount of wealth for a treeplanting company. In exchange this person receives pitiful percentage of the wealth being generated, all the sex they can handle, and life-long soft tissue damage to the back, knees, shoulder, elbow & wrist.
1. Ed: "Holy shit, did you hear how many trees Sam put in today?" Sally: "Yeah that guy is a total highballer."


2. Tina: "Holy shit, my knee hurts everytime I run & the doctor told me I've got the back of a retired coal miner." Tony: "Ya, you were the fastest planter ever though."
