pastposter
n.— «The casino industry’s first coordinated counterattack aimed at roulette pastposters, those plastic cylinders were invented by an ex-cheater working in surveillance for the Sands. Its purpose was to deny pastposters access to the winning chips underneath, as well as prevent the laying down of naked cappers.» —“Happy Thanksgiving” by Richard Marcus American Roulette Nov. 25, 2004.
