Pigs after all were held in great respect – as the signature animal for the Great Earth Goddess who controlled the winds — so no, instead one should only refer to them as ‘curly-tail’ or ‘turf-rooter’. Mentioning the banned word p̶i̶g̶ will result in strong, wayward winds, whilst going even further beyond the pale and actually killing a pig on board, will result in a full scale (almost certainly fatal) storm. Be warned.
