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.

Crash Course in Brain Surgery 

Look inside and you will see
The words are cutting deep inside my brain
Oh they're burning, quickly turning
Knife of words is driving me insane
Insane
Yeah, yeah

Raven black is on my track
Please show me how to neutralise the knife
Show to me in surgery
The art of fighting words to conquer life
Conquer life
Yeah, yeah

Ooh baby, I can rock and roll
Ooh baby, get out of my soul

Now the wicked lance of fear
Driven from my heady mouth and brain
Crash course in brain surgery
Has stopped the bloody knife of love again
Yeah, yeah, yeah

brain ninja 

Title given to girls by comedian Dane Cook. Girls have the power to fuck with a guy's mind by saying something so simple that it eventually drives them crazy.
