Double Napple Grapple: to squeeze both nipples of a friend until the point of pain.
Usually seen in goups of men, the double napple grapple is a method of showing affection in a
masculine way, often used in retaliation for a napple grapple recently received. To perform the double napple grapple properly both nipple
should be squeezed while counter rotating the wrists until the
recipient squeals in pain.
