ODP stands for Operating Department Practitioner
, basically a glorified nurse working in and around the operating theatres in a hospital, they generally think they are better than others, and can handle a GCSE level two year course based around the popular song "Dry Bones" ("With the toe bone connected to the foot bone, and the foot bone connected to the ankle bone, and the ankle bone connected to the leg bone..."). They make tea and fetch biscuits for surgeons and other more senior theatre staff, and stock medical supply cupboards. Sometimes they are entrusted with very basic clinical work, whereby the Trust can pay peanuts for monkeys. Other staff laugh at them behind their backs, because ODPs are generally quite chavvy.
