Sagging is a manner of wearing trousers or jeans which sag so that the top of the trousers or jeans are significantly below the waist, sometimes revealing much of the underwear. Sagging is predominantly a male fashion. Women's wearing of low-rise jeans to reveal their G-string underwear (the "whale tail") is not generally described as sagging. A person wearing sagging trousers is sometimes called a "sagger", and in some countries this practice is known as "low-riding". It has become popular since the popularity of wearing brightly colored and patterned "boxer shorts".
