A small, bullet-shaped device that stimulates the user by vibrating. It is usually inserted into an anus or pussy, or strapped to the penis or nipples with tape or an elastic band. Often has a distinctive design where the vibrating egg or bullet is connected to a wired controller (usually with a single knob) by a long, thin wire; this allows it to be identified even if the egg shaped head is not visible.
