Do you mean Mountain Dew the heavily-caffeinated soft drink, or Mountain Dew the slang for moonshine?
I remember when it was Jolt Cola, but Jolt’s heyday was short-lived. Mountain Dew is timeless, and is practically a stereotype by now. Red Bull is taking over a little though.
I don’t know about 5-Hour Energy, and I don’t trust it worth crap.
That’s their new marketing slogan.
