cuffing
n.— «Cheaters can be a problem, Mr. Crum said. Some cheats prefer a method called “cuffing,” in which “loaded” dice, weighted to land on a certain number, are slipped into a pant leg and stealthily pulled out during a game.» —“Rolling the Dice on a Warm Night” by Sarah Maslin Nir New York Times Aug. 16, 2009.
