dirty kitchen
n.— «Dirty kitchen (cont.): Actually, that’s the term for a secondary kitchen, often used by Filipinos. As one reader explained to me: “We Filipinos have a small cooking area outside the house where we fry our fish, cook anchovies, etc.—all that smelly stuff.…Filipinos love to cook, but we don’t want the smell and splatters in the real kitchen.”» —“Ah, romance and road hazards” by Steve Harvey Los Angeles Times Sept. 23, 2007.
