Loose fitting, oversized pants usually worn by weight-lifters. They're akin to parachute pants in that they are (usually) tightly cuffed at the waste and ankle, with the roomier part of the garment occurring around the leg and hip. Design wise, the fabric often mimics a zebra-like coloured pattern, usually featuring the primary colours of a significant sports team. It is a garment that goes very well with a hip-pack, a sleeveless muscle shirt and a mullet.
