the term "rubber chicken" is used disparagingly to describe the food served at political or corporate events, weddings, and other gatherings where there are a large number of guests who require serving in a short timeframe. often, pre-cooked chicken is held at serving temperature for some time and then dressed with a sauce as it is served. consequently, the meat may be tough or “rubbery.” someone who "travels the rubber chicken circuit" is said to do so by attending or making speeches at many such gatherings, often as part of political campaigning.
