A more specific type of grinch relative to the recreational smoking of marijuana. They are defined as a friend who brings over his/her marijuana to share with yours but, often put down an extremely smaller amount than what you do to smoke.
Trisha is such a Ganja Grinch. Every time we both put down some weed to roll into a blunt, she puts down this tiny little nugget thats about the size of my pinky nail.
