The 'It's Not Fucking Weed You Piece Of Shit Stoner' meme is a popular reaction image and text template used to aggressively correct someone who mistakenly identifies a common plant, herb, or object as marijuana. Characterized by its hostile and exaggerated tone, the meme mocks the 'stoner' trope of someone who is obsessed with finding cannabis everywhere they look. It gained significant traction on platforms like Reddit and Tumblr, often featuring characters from anime or pop culture looking visibly irate. The humor stems from the extreme overreaction to a simple mistake, making it a favorite for calling out friends or parodying drug culture online.
