An incompetent redneck will only drink beverages such as Budweiser, Cherry Coke, and mainly Mountain Dew. These rednecks tend to be blatantly drunk at any given time, but simultaneously energized by caffeine from energy drinks and of course, Mountain Dew.
Redneck: Whew, go Jeff Gordon!
Civilian: Damn they're annoying
Redneck: Cletus go grab me another six pack of Dew
Civilian 2: Yea, Mountain Dew-shBags too.
