Biggus annus is the Latin name for a woman whose arse resembles than of a small hippo.
Also the Latin name for the larger than usual woman name Anne.
This condition is caused by spending ones life gorging on a selection of donuts cake crisps and McDonalds to excess, like a human black hole and not walking for more than a few yards a day
When a biggus annus gets on the bus she needs to purchase two tickets.. One for each arse cheek.
