Has the most caffeine allowed in a soda.
Has 5 different flavors. Mt. Dew livewire, Mt. Dew Code red, Mt. Dew Baja blast (sold only at Taco Bell), Mt Dew Pitch Black and Original Mt. Dew. and is now sold in 14 oz cans in a 15 pack, which i think all mt dew lovers are screaming for joy about, to bad its limited edition.
Great for staying up all night at parties, doing homework etc.
Me:I love these new 14 oz cans of mt dew. To bad its a limited edition.

Friend: Ha! I think they will take it back like they say but then all soda will be 14 oz cans.

Basically a caffenated version of 7Up mixed with lemonade. Contrary to popular belief, Yellow 5 (the dye used to color the soda yellow) does not make your testicles shrink, but it does slightly lower your sperm count for about an hour or two after drinking.
Brittany wouldn't shut up about how her boyfriend was using Mountain Dew as a form of birth control. Now she's a 14-year-old mother.

Originally, a euphemism for moonshine, 'shine or corn licker. Now thanks to mass merchandising the name of a popular soft drink. Gives a whole different meaning to do the Dew.
Revenuers are on their way, best hide the Mountain Dew.

A Soft-Drink popularized by pictures of Counter-Strike and World of Warcraft Junkies sitting at their desks full of trash and desperately needing a shave. Outside of the internet, it is mostly known for causing health problems (i.e. the Yellow 5 dye, which may cause problems in the genetaila.)

It should also be noted that nothing from Mountains makes Mountain Dew, and there is no Dew in fact. There may or may not be Pitch in Mountain Dew: Pitch Black. For those of you who don't know what Pitch is, google it.
Guy 1: Look at this dude! He's got what, 50 cans of Mountain Dew stacked up beside his desk?

Guy 1's GF: That's disgusting.
