What is Nipple Ninja?
1.
A member of a not-so-secret and vaguely homoerotic society originating in Danville, California. A Nipple Ninja is fluent in many techniques of nipple flipping, and performs his art on unsuspecting victims. These moves (examples include: The horseshoe, the rainbow, the monkey wrench, and the Horny Hungarian) can be performed in friendly or unfriendly situations.
Holy shit, that Nipple Ninja just pulled a "guillotine" on Madlwski's fat nips.
