stooper
 n.— «The man, who declined to be interviewed, is part of a horse racing subculture made up of people known as stoopers. Much like people who spend afternoons wandering the beaches with metal detectors searching for treasure in the sand, stoopers spend their day at the track hoping to discover a discarded winning ticket.» —“At the Track, Fewer Stoop for the Payoff” by John Holl New York Times Aug. 2, 2004.
