Pantlessness (also called pantslessness, trouserlessness, or bottomlessness) is the state in which the lower body is exposed due to the lack of trousers.[citation needed] One event dedicated to pantlessness,[improper synthesis?] known as No Pants Day, is a participatory annual event that has happened in various nations[which?] on the first Friday in May. Another is known as the No Pants Subway Ride, which is an annual January event in which transit passengers ride trains without wearing pants. This is organized by Improv Everywhere, and it has been observed in dozens of cities worldwide.[dead link]
