I declare this phrase was
first used (uncredited) by someone, somewhere in the South as they were driving some old American
metal, shifted it into 2nd
gear, nailed it and yelled "Giggity giggity."
As
Jackie was driving her 1970 GTO down Buford Highway, she dropped it into 2nd
gear and gleefully yelled, "Giggity Giggity" as her passengers were thrown slightly back into their seats and her challenger was left in the
dust.
