8. Pear-shaped.
If you (as a woman) have a pear-shaped body, that means your hips are wider than your chest or shoulders, which could be good or not so good. If you have a pear-shaped voice, though, it is “rich and sonorous”, according to the Oxford English Dictionary. But if you’re in a situation that has become pear-shaped, look out, because it means things have gone horribly wrong. One theory says that the “horribly wrong” meaning comes from Britain’s Royal Air Force and refers to badly executed loop-de-loops in a plane.
