Generic replacement for Mountain Dew that one shouldn't purchase. Mello Yellow is considered generic as it is not Mountain Dew; despite it being produced by Coca-Cola. Most Mountain Don't's are produced by individual supermarket companies.
Characteristics of so-called Mountain Don't's include flat taste, lack of effect, and blandness.
Heee Haw (Hy-Vee), Citrus Drop (Kroger), Kountry Mist (Winn-Dixie), Mountain Breeze (Safeway), Mountain Lightning (Wal-Mart), Mountain Lion (Food Lion), Mountain Maze (Albertson's) and Moon Mist (Shasta/Faygo) are all Mountain Don't's.
