Any Cheetos lover knows the best part of the neon-orange snack is licking your fingers clean after polishing off the bag.  Now you’ll be able to practice the same repulsive ritual in Indiana’s Regal Cinemas.  Cheetos brand popcorn will soon be popping up as the new, classic movie theater treat in PepsiCo’s effort to push the profitable brand.  The treat will make its appearance on Dec. 22 at theaters in Avon, Fort Wayne and Indianapolis.
