dead water
n.— «Not all of the products look like water; they can be pink, yellow, green or blue. They don’t always taste like water—they may be flavored with cherimoya, pomegranate, sugar or herbs. And unlike regular H20 (or “dead water,” as it is sometimes called by enhanced-water marketers), these beverages often contain calories, although not as many as, say, a Coke.» —“Meet water’s cooler cousins” by Hilary E. MacGregor Los Angeles Times Jan. 16, 2006. (source: Double-Tongued Dictionary)
