Memoirs of a negro man 

A book that doesn't exist. Based on the idea that blacks don't/shouldn't know how to write.

Yeah, I've got the original Constitution on my bookshelf, right next to the Memoirs of a negro man.

Memoriast 

When you know you are making memory you will look past on in the future.

“Everything around me feels nostalgic as I imagine I’m walking through a surreal physical memory my future self is reminiscing on. I’m living in the future, creating the blinding memories that keep me stuck in the past.”

The experience of going to Disney World was Memoriast.

I feel Memoriast as I walk through the streets of Las Vegas.
