A "bulge" refers to a noticeable swelling or protrusion that can occur in various contexts. For example, when a tire is damaged, it may develop a bulge, indicating that the inner structure is compromised. This can be dangerous while driving, as it affects the tire's performance and safety. In a different context, a bulge can also describe a physical feature, such as a bulge in a person's abdomen. This might occur due to weight gain or pregnancy, and it can be a natural part of the body's changes. Understanding bulges in both scenarios is important for safety and health.
