brain ninja 

A person with the ability to insert thoughts or ideas into another's head that does not cause immediate, but rather long term lingering mental anguish, usually having comedic value.

Walk up to someone. Look at them thoughtfully for a moment. Sing, "I've got a golden ticket." Walk away. BAM, you're a 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.
