A trap, pony trap (sometimes pony and trap) or horse trap is a light, often sporty, two-wheeled or sometimes four-wheeled horse- or pony-drawn carriage, usually accommodating two to four persons in various seating arrangements, such as face-to-face or back-to-back. In the eighteenth century, the first carriage to be called a trap was a gig with a hinged trap door, under which was a place to carry a dog. In late nineteenth century USA, four-wheeled dog carts with convertible seats also started to become known as traps. "Pony and trap" is also used as Cockney rhyming slang for "crap" meaning nonsense or rubbish, or defecation.
