An act preformed by either a male or female on two males at the same time. The two males lay on their backs (boners in the air), the third party bends at the waist, legs straight (get a good stretch). The third party is now in position to "roll the dice". Now that the hand position similar to dice rolling is made place a hand on each of the said boners and get to rolling!
Barry: Hey buddy, let's go get Lindsay and see if she wants to play ankle dice.
Anthony: Lindsay is good, but let's ask Sarah... she's the high roller.
Barry: Keep on rollin'!!
