Most of the country forgets about the second “a” in caramel, and pronounces it with two syllables. The only parts of the country that say it with three syllables are the South and the East Coast.
“Pop” is used predominantly in the Northwest, the Great Plains and the Midwest. The word was originated by a British poet in 1812, who wrote, “A new manufacture of a nectar, between soda water and ginger beer, and called 'pop,' because 'pop goes the cork' when it is drawn.”
