Childlore is folklore passed directly between children, without the input of adults.

Stuff I can think of off the top of my head are paper fortune tellers, summoning Bloody Mary/the candyman, the cool S, parody songs like “Jingle bells Batman Smells” and “Joy to the world, the teacher’s dead” etc.
This stuff has intrigued me since, well since I was a kid. I always wondered where they came from. I never saw adults doing that stuff, so I figured another kid had to have come up with it.
You heard about that guy that took too much acid and couldn’t sit down because he thought he was a glass of orange juice and he would spill?
Ours was a kid on a band trip to Disneyland. Wouldn’t get off the teacups be wise he didn’t want to spill
All these “thought himself an orange and peeled himself” drug shit are bs propaganda that adults have come up with.
