Muffin top

A muffin-top (or "muffin top") is a slang term typically used to describe a man or woman's skin or body fat that is visible above the waistline of pants or skirts because of tight clothing. The term is a reference to the way a muffin appears when it has been baked in a muffin tin, in which the top of a muffin is wider than its paper casing. The term has been regarded as derogatory form of body shaming.
