Tracksuit pants. The lower half of a tracksuit. Often worn in Australia instead of shorts, trousers, jeans, skirts, dresses, slacks, etc, because they are comfortable. Acceptable attire amongst family, friends and neighbours (everybody loves good nieghbours). A derisive term when applied to strangers.
