groove
n.— «“The Groove”—Slang term for the best route around the racetrack. Drivers appreciate ovals that offer more than one groove, but a few years typically are needed before a new track develops multiple lines that can promote side-by-side racing.» —“NASCAR-ese” Richmond Times-Dispath (Va.) Apr. 27, 2004. (source: Double-Tongued Dictionary)
