"Soft drink" commonly refers to cold, carbonated, non-alcoholic beverages in the United States. Carbonated beverages are regionally known as:
"Coke", in most of the South, including New Mexico and much of eastern and southern Oklahoma. Some older generations of Southerners refer to soft drinks as "dope".
"Pop" in most of the upper Midwest and into the western part of the Northeast, including such cities as Cleveland, Ohio; Pittsburgh, Pennsylvania; Detroit, Michigan; Minneapolis-St. Paul, Minnesota; Erie, Pennsylvania and Buffalo, NY; west up to and including the Pacific Northwest; and as far south as the northern half of Oklahoma. The majority of the state of Michigan (including the Upper Peninsula), especially the Metro Detroit area specifically call soft drinks "Pop" (Faygo, a brand of soft drink made in Detroit is an example of this). In the lower Midwest, such as southern Illinois, southern Indiana, and the Cincinnati, Ohio area, "soft drink" predominates (which is why the term is used in Kroger stores, which is Cincinnati-based). The state of Colorado also uses the term "pop."
"Soda" in the Northeast, the Southwest (California, Nevada, Arizona, and Texas), Hawaii, and parts of South Florida (near Miami), and parts of the Midwest (around St. Louis and parts of Wisconsin, especially in the East, and around Milwaukee).
"Tonic" is used all over eastern New England although the usage is becoming archaic.
"Soda pop" is used by some speakers especially in the mountain west.
"Drink", "cold drink", and "soda" are locally common in southern Virginia and the Carolinas, spreading from there as far as Louisiana.
"Cold drink" is the phrase of choice in New Orleans, Louisiana.
At many restaurants in the U.S., one finds that the products of only a single major beverage producer, such as The Coca-Cola Company or PepsiCo, are available. While patrons requesting a "coke" may be truly indifferent as to which cola brand they receive, the careful server will confirm intent with a question like "Is Pepsi ok?" Similarly, 7 Up or Sprite may indicate whichever clear, carbonated, citrus-flavoured drink happens to be at hand. The generic uses of these brand names does not affect the local usage of the words "pop" or "soda", to mean any carbonated beverage.
