For the price, you can choose any two Spicy Chicken Sandwiches or two Checkerburgers / Rallyburgers, or one of each, plus a small order of Famous Seasoned Fries and a 16-oz drink.
The name plays off of the chain's "Two for" value menu, which features various pairings of sandwiches at several different price points.
