prop
 n.— «Keeping their annual tradition alive, oddsmakers at the Las Vegas Hilton sports book have released the world’s most comprehensive list of Super Bowl betting propositions. Other Las Vegas casinos will follow with their own propositions—or “props,” as they’re fondly known—on the big game, but the Hilton’s list is the biggest, best and most eagerly awaited.» —“Hilton releases Super Bowl props” by Jeff Haney Las Vegas Sun (Nevada) Jan. 24, 2008.
