A bulging waistline can be described using various synonyms, depending on the context and severity of the condition. Of all synonyms, a protruding belly is perhaps the most widely used term to describe an enlarged waistline. It suggests that the outline of the person's stomach is visible through their clothes, resembling a pregnant belly. Other words used to convey a similar meaning include a potbelly, beer belly, or paunch. These terms are slightly more colloquial and usually used to describe a slightly overweight person. On the other hand, a muffin top refers to the appearance of fat bulging over tight-fitting pants, particularly around the waist area, in women.
