snuse
n.— «As historians of the game know, sunflower seeds merely took over where smokeless tobacco, snuff—or “snuse” as it was called in the tiny Swede-dominated Iowa hamlet where I originated—left off. In those days, the boards on the dugout floor were brown-stained, as were what remained of the teeth of the multitude of players who chewed the nasty, not to mention lethal, stuff.» —“On the seedy side of sports” by John Lindblom St. Helena Star (California) Mar. 29, 2007.
