stooper
n.— «“The Stooper never had a losing day,” says Lacombe in ill-concealed envy. “He comes here broke, and the worst he can do is break even. Lots of win tickets go astray. Last year this track turned back $280,000 in uncashed tickets to the state.”» —“Professional Track Prognosticators Have Uncanny Ability” by Hugh A. Mulligan AP May 10, 1985.
