1. Talk the talk.
Get rid of your glaring gringo accent and learn to talk like an artesano. Greet other artesanos as amigos, even when you’re meeting for the first time. Use buena onda to describe anyone (or anything) you like. Throw around the English word “hippie” (pronounced with a Spanish accent: he-ppy) as an adjective.
Learn some regional slang to quickly understand your Latin American friends: parce means friend from Colombia, che is the ubiquitous greeting / salutation / word to insert after a sentence from Argentinos and Uruguayos, chévere sounds way cooler than “cool” and is often used in Peru and Ecuador. And learn to recognize curses: mierda, carajo, cabrón — just refrain from practicing them on your newfound amigos.
