Bacon is an unused upgrade which serves as some counter for how much bacon you have collected. Though there is a small button on the upgrades description tab on the bottom-left corner which you can press to purchase bacon. Purchasing bacon cost coins, and the cost will keep multiplying up by an unknown amount. Even though the price keeps multiplying, you can still purchase some even if you already wasted all your coins. It uses the pink X image as a placeholder.
