cowboy clicker
n.— «Watching television games doesn’t satisfy that hunger because my set doesn’t have what is known in coaching parlance as a “cowboy clicker”—a device that attaches to a VCR allowing plays to be run back and forth a million times at normal speed or in slow motion or frozen to allow precise study of offensive and defensive alignments.» —“Cutler reintroduces me to joys of watching tape” by Larry Beckish Island Packet (Bluffton, South Carolina) Aug. 11, 2006.
