Of course, you don't have to leave America to find different words for the same thing. For instance, an overstuffed sandwich may be called a hero, hoagie, submarine, dogwood, or torpedo. Depending on what part of the country you're from, you either put groceries in a sack or a bag. A sweet, bubbly drink in Missouri is called a phosphate. When you're in Chicago, it's pop. In New York, it's a soda.
