1. Pachyderm: Someone (or something) with thick skin. It is used for animals such as elephants, hippopotami and Dale Winton.

2. Mithridatism: The process of taking small amounts of poisons in order to build up an immunity to them. Named after King Mithridates VI, the King of Pontus, who, afraid of assassination, initially cultivated the process. (Mithridates VI also developed the 'Antidotum Mithridaticum', supposedly a universal panacea as it contained all known antidotes at the time of its invention).
