"Montezuma's Revenge" is not a disease. It is a "bad moment" that happens when a foreigner has never tasted chili or spicy food.
Its origin comes from Moctezuma, the mexica emperor who met the spaniards, as he now gets revenge on the foreigners (mainly whites, because spaniards are white) for destroying his people.
Its origin comes when Spanish conquistador Hernán Cortés entered the Mexicas' capital city: Tenoctitlán, he was beleived to be the god Quetzalcóatl (the mexicas had a toltec legend about a priest called Ce Acatl Topiltzin Quetzalcóatl, who fled eastward and vowed to return archaeological evidence suggests he fled to Chichén Itzá), who was said to be "tall, white and bearded". Cortés entered the city and was met by emperor Moctezuma "the young", who offered a meal in his honor. Having never tasted the local food, he eventually threw up and that's how the term came to be.
Typically created when there isn't enough liquor in the bottle to use by itself, or, when you really just want to get fucked up that night.
There is no real set recipe for Montezuma's revenge, just mix and match liquors and drink until you feel ready. It's not recommend to attempt to dance after you drank some, despite you feeling the urge too.
