montezuma's revenge

"Montezuma's revenge" is a colloquial term used to describe a type of traveler's diarrhea that is commonly experienced by tourists visiting foreign countries, particularly Mexico. It refers to an illness characterized by stomach discomfort, diarrhea, and sometimes vomiting, often caused by consuming food or water that is contaminated with bacteria, parasites, or viruses. The phrase draws its name from Montezuma II, the last Aztec emperor of Mexico, and is a humorous way to relate the experience of travelers falling ill while visiting the country.
