Gross, often referred to as disgusting, describes something that causes a strong feeling of revulsion or nausea. This can include sights, smells, or tastes that are unpleasant, such as spoiled food or unsanitary conditions. People often react to gross things with a physical response, like gagging or recoiling. Common examples of gross items include moldy bread, rotten fruit, or insect infestations. These items can trigger a natural instinct to avoid or remove them due to their potential health risks. Understanding what is gross helps people maintain hygiene and make better choices about their environment and food.
