STP
An old adage from the 1960s to the 1980s, during the Indianapolis 500 glory days of the partyin' Snake Pit in Turns 1 and 4, meaning to "Start The Party." Of course, this was before the evil Tony George took over the Indianapolis Motor Speedway and made it family-friendly.
Hey Joseph, when will they STP during the month of May at the Speedway?
