oh something I noticed the other day @petrichor  and @Appleblossom . I think it mainly means just taking your shoes off and having some healthy outside time.

Sometimes, people are a bit mean with it though. Like internet debates getting heated and one telling the other to touch grass. In a sort of caring but also sort of ...... undermining or something.

It's also used a lot as just a positive thing to do. Now I'm thinkin' you could put grass in your socks. Grass grows all over the place. You could stuff your socks with it. Not quite the same but might be nice.
