Apparently, there are also places called Montezuma (as I'm finding out here) - but what you mean probably refers to the Aztec ruler Montezuma, or Moctezuma (and more correctly Montezuma/Moctezuma II), who was the Aztec ruler met by Hernán Cortés. (

Or maybe you mean Montezuma's Revenge, which I see is a '"a colloquialism for traveler's diarrhea in visitors to Mexico. The urban legend states that Montezuma II initiated the onslaught of diarrhea on "gringo" travelers to Mexico in retribution for the slaughter and subsequent enslavement of the Aztec people by Hernán Cortés in 1521." It's also a video game from 1984 (

This guy's everywhere! Kinda like Trump and everything he put his name on? (Trump steaks leading to Montezuma's revenge?)
