The 'This Edible Ain't Shit' meme is a popular internet format that humorously depicts the overconfidence people often feel shortly after consuming cannabis edibles, followed by a sudden and overwhelming onset of effects. The joke typically follows a two-part structure: a character expresses skepticism about the edible's potency, followed by a jarring visual shift into a psychedelic, chaotic, or absurd scenario representing the moment the THC finally hits. The phrase became a viral catchphrase on Twitter and Tumblr around 2017, evolving into a versatile template used to describe any situation where a person underestimates a looming challenge or a drastic change in circumstances.
