City slicker, the term used to describe a person who is slick or sophisticated in a big city, is often considered an insult to people who prefer rural lifestyles or small-town living. Antonyms for this word could include country bumpkin, hick, or yokel, describing someone who is an unsophisticated or naive person outside of the city. These words don't have to be considered insults, but rather embody a different way of living and perceiving the world. It's important to remember that no matter what lifestyle you choose, it's equally valuable and worth respecting.
