Untidy heaps are a common sight in many places, often referred to as messes. The term 'untidy heaps' is used to describe piles of objects that are not organized or arranged in an orderly fashion. These messes can be found in homes, offices, and other public spaces, and can range from small piles of paper to large piles of debris. In some cases, untidy heaps can be hazardous and can lead to health and safety risks.
