Montezuma's revenge
The colloquial term for any cases of traveler's diarrhea contracted by tourists visiting Mexico. The name humorously refers to Moctezuma II, the ruler of the Aztec civilization who was defeated and slaughtered by Hernán Cortés, the Spanish conquistador. The white Spainiards would then continue to enslave or obliterate the Aztec people.
It is said that whenever a white person has diarrhea while visiting Mexico, he is suffering the wrath of Montezuma's revenge.
