The map below comes from North Carolina State University's Joshua Katz, who has mapped all kinds of dialectical differences between different areas of the country.
One of the most polarizing questions he asks: What do you call a sweetened carbonated beverage?
Nearly half of the country — 47 percent — refers to it as "soda," while 23 percent say "pop" and another 19 percent go the proper noun route and say "Coke."
The real maniacs, though, are the 7 percent of people who call it a "soft drink." Who talks like that!?
