A "mack" or flirt where a man, well hung, by placing his dick on a womans leg, arouses her to satisfy him orally.
Man: "I walked into the room, placing my member on her heaving thigh as she slept. Upon waking to the sight of such an appetising morsel, she proceeded to indulge in an early morning protein shake."
Friend: "Oh yeah! You totally
pulled off the dick on leg move!"
