sharp
n.— «Knowing whether a line move is due to sharp or public action is important. A sharp is a term used to describe those who make a living off of sports betting. They wager large sums of money at numerous books, in hopes of gaining an edge. By no means are these folks always right, but their decisions are always well informed.» —“Where the smart money goes” by Sean Murphy Covers Experts Mar. 20, 2007. (source: Double-Tongued Dictionary)
