Touch grass became a staple piece of internet slang in the early 2020s, spreading through Twitter, TikTok and Twitch streams as a quick way to call out someone who seemed too absorbed in online arguments. The phrase caught on because it was short, visual and easy to drop into replies, edits and reaction videos, turning a simple suggestion to go outside into a meme insult. It has stayed popular because online debate has not slowed down, so creators still use it whenever a clip needs a fast, recognisable shutdown.
