A piece of sport practised at wakes, horse-races, and fairs in Leicestershire: a cock being tied or fastened into a hat or basket, half a dozen carters blindfolded, and armed with their cart whips, are placed round it, who, after being turned thrice about, begin to whip the cock, which if any one strikes so as to make it cry out, it becomes his property; the joke is, that instead of whipping the cock they flog each other heartily.
