Weed knight

a weed knight (or green knight) is similar to a white knight, though instead of running to a woman's aid whenever she faces the slightest resistance, weed knights focus on defending the funny plant theyre addicted to. If at any point weed is said to not be some kind of miracle cure or god forbid someone says its addictive, the weed knights are sure to come to make sure the lead theyve based their entire personality on isnt scrutinized

John: "I think youve got a cannabis-addiction man"
Jack: "nah I can stop whenever I want, I just choose to do it every day! Besides, alcohol is way worse for you!"
John: "yeah we all know alcohol isnt any better, but at least im not an alcoholic! Stop being a weed knight and admit youre addicted"
