"LA MENTIRA" (The Lie) is Nathy Peluso turning the lie into a glamorous character and then roasting it. The lie "se disfraza de perra empaquetada" [dresses up as a dolled-up bitch], flies business class in Gucci ojotas (the Argentine word for flip-flops) and runs the TV. Against all that noise she offers one piece of advice: "No todo lo que te pesa en el cuello es oro" [Not everything weighing on your neck is gold], her take on "all that glitters is not gold".
The song is packed with references worth decoding. "Los ojitos como Bowie, uno negro y otro azul" [Little eyes like Bowie's, one black and one blue] nods to David Bowie's famously mismatched-looking eyes. Espidifen is a Spanish painkiller brand, so "Nada está del todo fine / Pero tengo Espidifen" is a very funny way of saying "not great, but I have pills". You will also hear River Plate slang everywhere: guita (cash), che (hey), una bocha (a ton) and tu vieja (your mum). The ending is surprisingly sweet: when your mum asks if you are happy, don't lie to her.
