Dogging is a predominantly British activity that involves outdoor exhibitionism in car-parks, wooded areas and the like. The term dogging originated in the early Seventies to describe men who spied on couples having sex outdoors. These men would 'dog' the couples' every move in an effort to watch them. When the swinging scene discovered that open-air sex has its own special thrill they began meeting in car-parks, and the doggers found a new and rich supply of voyeuristic fun.
