Question

High Horse acting superior and arrogant as if you were better than other people

Accepted Answer

I wish that new girl in drama class would get down off her high horse. This saying goes back at least to the early 1700s. In the 14th century, during ceremonial marches and royal exhibitions, well-known people of high rank and superior position in society often rode on large horses that were taller than the average horse. From that custom grew the idea that a person who acts haughty, proud, or snobby is on a "high horse."
