1. A polish surname
2. A noun or an adjective used to describe an irreverent/eccentric man slightly better than a mannequin: tall, fit, eyeliner wearing, slightly sexually deviant, clever, well spoken, and dresses in current hipster fashion. Unlike mannequins, this man is likely to be pierced in various places. He identifies with robots and machines because, like him, they never sleep.
