Are you easy to tick off? Known to have a short fuse? Then, you could be described as choleric. Don't worry; it's not a disease related to cholera. Choleric just means you're testy and irritable.
Before the advent of modern medicine, most folks believed that health and disease were the result of the balance of "humors" in the body. If you were quick to anger, you were thought to have too much choler in your system. You were called choleric. W. C. Fields, Richard Nixon, and Ebenezer Scrooge are just a few people famous for being choleric, easy to tick off.
