Pogago
The word "pogago" is a potato when served on a Chinese buffet, especially when served as "pogago skins." Not normally Chinese-style food, this word has more recently come to represent those foods served in restuarants that don't fit the overall theme of the restaurant itself, or even someone who changes the subject of a conversation abruptly.
Examples: "I went to a Mexican restaurant today and they had pizza on the menu. That's such a pogago." "John's a pogago. We were talking about the nice weather, and he suddenly mentioned that he needs to get his oil changed."
