I have to call into question the area they said Bart was used when referring to "what do you call a public railway system(normally underground)". They did not highlight the actual area where Bart runs (The San Francisco bay area) but an area where Bart doesn't even exist. Seems like if anyone was to say Bart it would be in the area Bart was available.

-edit-
Information came from these maps and on the Bart issue the maps had it right but the video goofed it. Its #104 http://spark.rstudio.com/jkatz/SurveyMaps/ (where the video said it got its info from)

Then again maybe I'm being way to nit-picky as I'm guessing some would say it's close enough. That all being said it is quite the cool video.

This video probably could have lasted 10 minutes longer and it would have retained my fascination.

And it's not "MUTE"!

In San Antonio they always said "soda water" for any soft drink, I don't know why they didn't just say soda like we did in NY. Also they could have included "grinder", which is what they call a sub in Connecticut. When I first moved to CT I couldn't imagine not calling it a sub, but then when I later moved on to TN they looked at me strange when I ordered some grinders to go.

Despite living in Minnesota my entire life I find I prefer using the term soda over pop, I guess at some point I just thought pop sounded kind of stupid.

Same here (upstate NY).

To me Soda sounds wrong and doesn't make sense. I immediately think of Baking soda or something similar

Some chemical compounds containing sodium
Sodium carbonate, washing soda or soda ash
Sodium bicarbonate, baking soda
Sodium hydroxide, caustic soda
Sodium oxide, an alkali metal oxide

I think of soda because the first thing I associate with that word is soda water, which I guess is kind of the origin of soda anyhow. But if you're more chemistry oriented I could see someone coming up with a different image, baking soda would probably be next on my list after soda water.

There's a huge difference between urban and rural dialect, particularity in the mid-west that isn't reflected in this video. Some of these examples emphasize stereotypes that are actually in the minority. Fun none the less though.

We say Soft Drink in Australia. Kinda weird, not sure where that comes from

Because historically, Australia was fulla drunks and rounders, the exiled and the wild-
Blame Prohibition in the U.S. for the terminology: “Soft Drink” refers to most beverages that do not contain an inordinate amount of alcohol (hard drink)-Booze bees the culprit, although a lifetime of soda on the tummy is as hard a drink as you can get as far your stomach-lining is concerned.

Hmmm, makes sense. I guess over time it came to be used to refer to just carbonated drinks/sodas

Ditto. I said pop as a kid, somehow transitioned to soda. Michigan, here.

Also, surprisingly, I pronounce pecan the way they do in Texas. hmm

I remember when I moved to Texas and someone asked me if I wanted a Coke. I said sure. He asked what kind of Coke. I said uh regular? I had no idea that in Texas, every soft drink is a Coke.
