Argentines are known for being brutally honest. The common extranjero may interpet this as utter rudeness, running home in tears after being called a major fatty. Political correctness does not really exist compared to the out of control politically correct attitude in the US. Gain a few pounds? Looking rough in the morning after a long night out? No need to worry! I guarantee you’ll have several “friends” to call you out on it… “Estás más gorda! Qué estás comiendo?” *Basic translation: You are a fat ass, put down the fork and wire your double chinned jaw shut.
While you may think calling someone gordita (fatty), grandota (giant beast), negra (someone who is dark skinned), or china (Asian, or some with Asian features, or someone with curly hair?) isn’t very nice, it is used more as a “loving” term of a endearment.
Heading out to a costume party? Don’t be surprised if you see a number of inappropriate outfits, I’ve seen people dress in black-face, Nazi gear, and KKK robes. In my opinion, there are two things at play here… those foreigners who are way too sensitive, and those Argentines who do not know when to shut it.
