Ask ten people to picture a sex toy and a good number of them picture this one. Two ends, two jobs, both at the same time. Rabbit vibrator, rabbit dildo, bunny vibe: the name moves around, the shape doesn't. A curved insertable shaft with a smaller arm out front.
Where they differ is underneath. Some run the two ends on separate motors, so the shaft and the arm can go at different speeds or different patterns. Some thrust. Some rotate. Some have beads in the shaft that churn. Sizes run from palm-sized to conspicuous.
Everything above is a rabbit.
