I learned what Haughty meant on my 11th birthday, because I got Civilization 5. It was newly released. I played as China that night and recall the narrator calling Wu Zetian (I still remember her name) the Haughty Empress of China. Since I was 11 I perceived this as 'the Hotty Empress of China' and asked my parents why they called her a hotty. They explained the alternate version of the word.
