A very large, ribbed metal penis. It isn't attached to a person but yet has a mind of its own. It enjoys penetration of all sorts.
A dark shadow fell across the land, and everyone knew that the mecha peni had arrived.

Giant robot. Refers to humanoid types seen mostly in animé (Japanese cartoons) and Japanese games (i.e. Armored Core). Mechs/mecha can be anywhere from 30 to a few hundred feet tall and are usually pioleted by people. They can be used for many things, like constuction for example, but more often warfare.
The mech picked up the car and threw it at the V.I.P.

A mechanical goose, half goose, half robotic. Most times it has a sad back story with an arch rival such as Evil Duck.
