Colloquialisms

Even in my current state – physiologically weakened as it is – this passage from Wikipedia struck me as funny.

There are a number of colloquialisms for travelers’ diarrhea contracted in various localities, such as “Montezuma’s revenge”, “turistas”,[27] or “Aztec two step” in Mexico; and “Pharaoh’s Revenge,” “mummy’s tummy,” or “Cairo two-step” in Egypt. Many other colorful synonyms exist in other regions of the world, some of which have found their way into the arts and literature. For example, Aamir Khan titled his 2011 Hindi film Delhi Belly, after the popular Indian colloquialism.
