Sponging is a method of cleaning or absorbing liquids using a sponge, a porous material that can soak up water and other fluids. This technique is commonly used in households for tasks like washing dishes, cleaning surfaces, and mopping up spills. Sponges come in various types, including natural sponges from the ocean and synthetic sponges made from materials like cellulose or polyurethane. In a broader context, sponging can also refer to the behavior of relying on others for support or resources without contributing in return. This term is often used in social discussions to describe individuals who take advantage of others' generosity, similar to how a sponge absorbs without giving back.
