Hidden Ninja

When someone is about to perform oral services to a male, the male tucks his penis between his legs when the performer isnt paying attention. When the performer's face is close enough to the penis the male opens his legs, resulting in a surprise attack to the performer's face.

Johnny did the "hidden ninja" on Hailey, and she broke up with him.
