The term "casual" refers to a relaxed and informal style or attitude. When someone dresses casually, they might wear comfortable clothes like jeans and t-shirts instead of formal attire. This approach is often seen in everyday settings, such as hanging out with friends or going to a casual restaurant. In social situations, being casual means being laid-back and approachable. People often engage in light-hearted conversations without strict rules or expectations. For example, a casual gathering at home allows friends to enjoy each other's company without the pressure of formalities, making it a more enjoyable experience for everyone involved.
