Language is always changing. It's fascinating to learn how the same language evolves differently based on where the speakers live. Slang words that are completely natural to one region can get confused reactions in another. Given the size of the U.S., there are so many opportunities for multiple slang words with the same meaning to pop up throughout the country. Here are a few words that are used differently depending on where you're at.
In Texas and other Southern states, many people call all soft drinks "coke." That's because Coca-Cola, which started in Atlanta, became so popular that its name came to mean any soft drink, a process called genericide.
If you're in the Midwestern or Western states, "pop" is the most popular term. "Soda" is used most frequently on the coasts, with California and New England states preferring it. But in one New England state, Massachusetts, many older people use "tonic" to describe their bubbly drinks.
Much of the U.S. calls athletic shoes "tennis shoes," though we wear them for much more than tennis. The Northeast and a small part of Florida are the only areas where "sneakers" is the most popular term, because you can sneak up on someone with the quieter rubber soles.
People in a small area of the Midwest, mostly around Chicago and Cincinnati, call their athletic shoes "gym shoes." People in Hawaii often call them the generic "shoes."
Many Americans would say, "Grab a cart," when grocery shopping, but that isn't the only term used to describe the wheeled basket. Much of the South calls it a "buggy," and the Northeast calls it a "carriage."
Hawaii actually uses "wagon," a term similar to "carriage" and "buggy." If you go outside the U.S., the most common name for it is a "shopping trolley," or just "trolley."
The use of "drinking fountain" versus "water fountain" seems to be split pretty evenly. From Eastern New Mexico, Colorado, Wyoming, and Montana to the East Coast, "water fountain" is most popular. The Western states and those in the Great Lakes area use "drinking fountain." But there is an even smaller area within the Great Lakes where they call it a "bubbler."
Milwaukee, Wisconsin, is the main area where "bubbler" is heard in the U.S., though it is also heard in parts of Rhode Island.
Outside of the Southern U.S., when you hear the word "toboggan," you'll think of a sled. But in the South, a toboggan is a knit winter hat. Most of the other areas in the U.S. call it a "beanie," after the old slang term for your head: "bean."
The summertime insects that give off a glow at night are either "fireflies" or "lightning bugs," depending on the area of the U.S. The South and the Midwestern states prefer "lightning bugs," while the rest of the U.S. chooses "fireflies."
