Bélica is the feminine form of bélico, which literally translates to "warlike" or "bellicose". While it sounds like a formal word you'd find in a history book, it has become a key piece of modern slang in Mexican music.
In this song, Peso Pluma uses it to describe a certain style and attitude associated with his music genre, corridos bélicos. When he sings "Pura encapuchada bélica" (purely 'bélica' hooded girls), he's describing women who are bold, tough, and part of an edgy, assertive culture. It’s a perfect example of how a classic word can take on a new, powerful meaning in pop culture.
This song is a straight-up description of a wild, luxurious party lifestyle. Peso Pluma and his friends are living large, and they want you to know every detail. The song kicks off by listing the party essentials: "Dom Pérignon, Lady Gaga, lentes en la cara, tussi y lavada" (Dom Pérignon champagne, Lady Gaga, glasses on my face, tusi and washed cocaine). It's all about private islands, yachts, and spending huge amounts of money, or as they say, "tronamos las pacas" (we blow through the stacks).
What's interesting is the kind of company they keep. They're with women described as "una bandida que me llama, quiere mi lana" (a bad girl who calls me, she wants my cash), and he's totally fine with it. A key rule of this world is discretion; the women they're with don't post on social media: "Ninguna sube nada al Instagram / Sólo disfrutan" (None of them post anything to Instagram / They just enjoy themselves). The whole track feels like a glimpse into a secret, high-stakes world of narco-culture glamour, where everything from a woman's waist to a simple greeting costs a fortune—"Cada saludo lleva un billetón" (Every hello comes with a big bill).
