The belt still has an important utility use for men and is also a weapon in the war against 'sagging'. 'Sagging' is the fashion for teenage boys, and men in their 20s who don't know any better, to wear their jeans practically falling off them so that their underwear is exposed. Seeing 'sagging' makes me think of fat camp and a sign of extreme weight loss. Many schools now insist that boys wear belts specifically around their waists.
