The single most addictive, non-alcoholic drink I have ever encountered. I got hooked on it at an American airbase and I had withdrawal symptoms when i returned back to Newcastle. It tasted alot like a drink we used to have here called Tab, whatever happened to that?
I crack open a can:
mmmm sweet nectar, gotta have more, more, MORE!!!!!!!!!!!!!

Redneck Holy Water. The most popular drink amoung rednecks. A Mountain Dew flag should be made and flown right under the confederate flag. Or as rednecks call it the "rebel flag."
Quite possibly the only spit bottle you will see being used or scattered amongst the numerous fast food bags in the floorboard of a truck.

A carbonated beverage made by PepsiCo. Highly caffeinated for a soda (55mg per 12oz compared to 80-135mg per 8oz of brewed coffee). Advertised as an "extreme" drink in commercials, with people participating in extreme sports, often grabbing a can with one hand while upside down in mid-air performing an extreme stunt, and chugging it all. Mountain Dew claims a large variety of flavors, in order of creation:
Mountain Dew
Mountain Dew Code Red (Cherry)
Mountain Dew Livewire (Orangish)
Mountain Dew Pitch Black (Grape)
Mountain Dew Baja Blast (Tropical Lime)
Mountain Dew Pitch Black 2 (Sour Grape)
PepsiCo also creates diet flavors of Mountain Dew drinks. Also, there are two drinks marketed as energy drinks:
Mountain Dew AMP
Mountain Dew MDX
AMP is bottled in the classic energy drink style, a slendar aluminum can, while MDX is bottled in a smaller, more unique style of platic bottling. An enjoyment of all Mountain Dew flavors is that each flavor holds the taste and kick of regular Mountain Dew, along with its separate flavor, with the exception of Pitch Black and Pitch Black 2, which arguably don't hold the taste of regular Dew.
"Yo, bro, stop here. We need to pick up some Mountain Dew."
"Yo, for real, thats extreme."

In the night of the Last Supper, as the story is told, Jesus took bread and wine and blessed them. The actual use of bread is unknown, but recent research has shown that the Blood of Christ was not wine, but Mountain Dew.
... again after supper he took the cup, gave thanks and gave it for all to drink saying "This is Mountain Dew. Let it live for eternity as the drink of Jesus!

Mountain Dew, a highly caffinated drink. Good for a pick me up when meth is not available. WARNING! Do not make Mountain Dew your only consumable liquid! It causes kidney stones! Seriously!
Johnny was feeling spent so he drank 10 bottles of Mountain Dew and stayed up for 12 hours playing Mystery Date.
