A modern day version of the phrase Rags to Riches, among college students, referring to the change from Natural Light (Natties) to the classy Bud Light Platinum (Platties). Indicates that one has earned money and made their own way in the world, and is showing improvement in their financial status in life.
After scoring a summer internship at GE, Eric had a ton of money and was able to pay off all his debt for the year. It was truly a Natties to Platties story.
