So, to refresh my memory, I Googled "The Secret World of OG."
Wikipedia:
... Accompanied by their fearless pets, the children descend through a secret trapdoor into a strange underground world of mushrooms ...
Undoubtedly Magic Mushrooms, Pryde ... which undoubtedly explains why you know more about this than do I. 😉

LOL ... dollars to donuts, you have experimented more with that kind of stuff than I. I am pretty straight-laced outside of my imagination.
The children travel to a realm where the inhabitants communicate with one word ... OG. Unless they communicate by derivation from the comic books they have stolen from the children over the years.
Very apropos to what is happening now. I read it as a kid but I imagine an adult would enjoy it too.
Og, og, og.
