Che boluda... ¿qué te pasa? Estás como loca hoy.
Hey silly [potentially insulting, not amongst close friends]... what's up? Today you're like crazy.
Caption 3, Cuatro Amigas - Piloto - Part 3Play Caption
Our third installment of Cuatro Amigas – a very Sex and the City-like Argentine drama – opens in the ladies' bathroom, where we get a chihuahua's eye view of Elena and Rita's taste in intimate apparel. They are chatting intimately, addressing each other with che in caption 3 (cited above) and again in caption 14. In Argentina, che means "hey" between friends, or even "yo." Basically, it's a familiar, informal attention getter... che, got that?
If you watched 2004's Motorcycle Diaries, chronicling the cross-continent journeys that raised the consciousness of Ernesto "Che" Guevara, you know how Che got his famous nickname. For the rest of you: The Chileans were simply making fun of young Ernesto's Argentine habit of saying che all the time. (For more lore about the Marxist revolutionary, look for the two-part 2008 biopic called Che, with Benicio del Toro as a very convincing Che.)
Back to the quote cited above, which is translated as, "Hey silly, what's going on with you?" But we put a special note next to our translation of "silly" because that's not the whole story. Boludo or boluda is a slang word in Argentina that roughly means something more like "jerk." Use it with caution in the streets of Buenos Aires because it can be quite an insult, depending on the context. But between girlfriends, it's almost another way to say "hey... you."
