Used to describe a fandom that is utterly insane.
“One thing I love about Hazbin Hotel is the fandom! The series has such a thriving society of followers of the truth, a mess of tangled limbs danced around my bedroom, I held my breath, and waited for it to stop, I was too scared to move…”
A society that includes only people with smooth, silky brains who consider themselves as "smart", Except for the Head and co-head that are just heads instead of brains.
Example:
"Hey, I'm Sean from the Smooth Brain Society"
