earthkeeper
A dumb hippie word for someone who thinks plants are cool and tries to save the planet by not throwing trash on the ground. Basically a tree-hugger with a bad attitude.
My science teacher called me an earthkeeper because I recycled my lunch wrappers.
I got mocked in the hallway for being an earthkeeper and wearing a hat made of leaves.
My dad said I was an earthkeeper because I complained about littering.
