A Naco is a combination of nachos and a taco served at Bueno Nacho. It is created by taking nacho chips and cheese, mixing them with the fillings of a taco, placing it all in a tortilla, and lifting up the sides to form the bag-like shape. The Naco was invented by Kim's sidekick Ron Stoppable. In the episode "Ron Millionaire", through the vast popularity of the Naco, Ron received a royalties check for 99 million dollars two years after his invention: "A nickel for every Naco sold". That equates to almost two billion Nacos sold in one year (specifically 1,980,000,000).
