A figgin is defined in the Dictionary of Eye-Watering Words as 'a small short-crust pasty containing raisins'. The Dictionary would have been in­valuable for the Supreme Grand Master when he thought up the Society's oaths, since it also includes welchet ('a type of waistcoat worn by certain clock-makers'), gaskin ('a shy, grey-brown bird of the coot family'), and moules ('a game of skill and dexterity, involving tortoises').
