Some chick just stopped by my cube and mentioned that Mt. Dew is a boob shriveller. Any truth to this… I knew exactly where to bring my question… to take the straight dope back to her.
No more than it will shrink testicles, I would wager.
Straight Dope Article on the Mountain Dew = shrinking secondary genital characteristics? issue.
Although in the case of breasts, who knows, there may be something to the caffeine and sugar so that as your bod becomes less fit, they droop.
I find it totally implausible that there would be a widely available foodstuff that affects the size of breasts, yet the only source of that information is word of mouth. With Mountain Dew having been around for decades, and its various ingredients for much longer, how could such a thing be true but not be well-documented common knowledge? Not meaning to be snide, but that “chick” isn’t very bright to even begin to believe it.
Hi sweetie, welcome to Raisins!
Hell, it certainly increased the size of mine.
Dammit.
I don’t know, I drink my fair share of Mt. Dew and I got a nice set of man-boobs going here. Maybe it’s because I only drink diet Mt. Dew?
HAHA!!! 
Would it be ok if it made them bigger?
