The way mushrooms make your body feel. The good feeling of moving parts of your body (like fingers, toes, tongue, cheeks, nostrils) and rubbing them against each other during a mushroom body high. It does not describe the spiritual insights (like unity or harmony with the universe) or visual experiences (like colors, glowing or streaking) that are associated with mushrooms. The word can also be used to describe the imaginary woodland reality that mushrooms inspire. For instance, a picture of a psychedelic gnome can be gnorky.
"Look at Nate flexing his fingers and rubbing his feet together - he must be feeling gnorky."
