The rabbit vibrator, also known as a Jack Rabbit or Jessica Rabbit is a vibrating and rotating sex toy, usually made in the shape of a phallus with a clitoral stimulator attached to the shaft. However, the rabbit vibrator has evolved to reach a wider market, with many new introductions that do not take a phallic shape. The name of the device is derived from the fact that the clitoral stimulator looks like a pair of rabbit ears.
