The (theoretical) opposite of the soda Mountain Dew. The name is derived from the antonyms of the words making up the name of the aforementioned soda. Presumably, as Mountain Dew is thirst quenching, sweet, and highly caffinated, Valley Dust would be intensly (perhaps fatally) dehydrating, sour, and coma-inducing.
I refuse to drink Valley Dust, as it almost knocked me out the last time I had it.
