Grassmaster 

One who has mastered the art of the smoke. One who has achieved calm in both mind and breath. One who is truly meant to be worshipped and observed.

Fuckboi friend 1: Geez, how many joints has Andrew done already?
Fuckboi friend 2: SHHHH!!! Silence, knave! Lest thou value thine puny existence, thou shalt NOT interrupt the one true Grassmaster in the middle of his ritual! Have thou no shame?!
