"High thoughts," almost like shower thoughts, but driven by weed and, in my experience, learning an interesting fact or tidbit.
So they're not a scientist and don't have formal training in sounds or plants or animals, they learned a fact and got high and connected some dots, haha
imagine a shirt that says "I'm not a scientist". it's basically that but if you smoke weed you are obligated to tell everyone unprompted, so this is for weed smokers who want a shirt that says I'm not a scientist.
