a phrase used as a response to an individual who either disproves a premise, states an unsatisfactory opinion, or otherwise agitates the person in question. While the phrase implies that a person doesn’t go outside to know what grass feels like, it’s often the speaker themselves who has an overweight or diminutive build. Note that in most cases, the topic of conversation has nothing to do with fitness, sociability, or anything involving the outdoors.
Ex.
Non-Blue Check user: “Imagine thinking that LGTBQ people aren’t just doing it for attention.”
Blue Check: “Why don’t you touch grass, bigot”
