Anus Horribilis
When you have a wicked case of the shits that lasts an entire calendar year.
After her Annus Horribilis — or "terrible year" (1992), which saw Windsor Castle burn and her childrens' lives marred by divorce — Queen Elizabeth II developed a case of Anus Horribilis. It was so bad Prince Phillip had to sleep in his own room. Not even the royal corgis could stand the stink and the constant trips to the loo.
