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"

Boy brain

When a guy says some outworldly primal shit that can only be construed as an act of machismo.

This guy was telling me of how it's his dream to die in WW3. What kind of boy brain shit is that?

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.
