Brain Sister

A "Brain Sister" is a girl who wears glasses and finished high school. However, there is some debate as to whether or not a "Brain Sister" actually wears glasses.
"She was only twentyseventeen, she was a lonely beauty queen, she was a brain sister, Texas Instruments all day..."

Quoted from the Limozeen song "Brain Sister"

foreskin brain

The foreskin creates electrochemical signals that are communicated to much of the body, including the brain. Information about sensitivity, arousal, compassion and the importance of physical touch. Circumcised, they are all nonexistent or at least minimal.
There exists similar information at a website search for “penis brain” by wordpress.com but, I’m afraid it neglects to mention the equally important and powerful part that a healthy foreskin play’s in sexual and mental health.
The foreskin brain is key to sexual intercourse being a fully humane experience and not just an organismic relief.

brain ghost

A figment of one's imagination which occurs as a result of one's brain filling in gaps in information unnecessarily.

They can be sights, sounds, tactile sensations, or even an uncomfortable feeling a presence. They are distinguished from ordinary hallucinations by the fact that all people are prone to these phenomena, and the person need not believe the brain ghost to represent reality, although some do.
A person's blind spots are an example of a brain ghost.

"I was alone in my house when I felt the presence of a ghost."
"Ghosts don't exist; it must have been a brain ghost."

"I thought I heard a baby crying, but upon realizing that I was alone, I realized it was a brain ghost."
