Don't ever ask "Where does pisco come from?" if you have Chileans and Peruvians together. The same goes for the question of the arepa--the fights between Colombians and Venezuelans over its origin are never-ending. Most of the time, there will be some shouting: "¡Qué mentiras!" and other assorted choice words (some not so pleasant), but hopefully no one will stay mad for long. Like these, there are several other issues that will guarantee a fight between Latinos. Let me tell you what they are.
