Pacas is popular slang in regional Mexican music for "stacks of money", referring to large bundles of cash. This informal term is essential for understanding the themes of wealth and success in the genre.
In the lyrics, Junior H sings "Las pacas son para gastarlas" (The stacks are for spending them), showcasing the lavish and carefree "rockstar" lifestyle. It's a perfect example of the kind of modern slang that will make your Spanish sound more authentic.
Junior H lays out his very specific relationship philosophy in "ROCKSTAR." He's not trying to be a perfect boyfriend, and he's totally upfront about it. He calls himself a "niño triste, rockstar, soy maldito" (a sad boy, a rockstar, I'm cursed) and admits he's not the handsome type. The relationship he describes is built on an understanding: she doesn't get upset when she sees him with other women, and he knows nothing scares her. It's a partnership that avoids drama.
Instead of fighting, their solution is to "prendemos los blunes / Lo hacemos con canciones" (light up the blunts / we do it with songs). He's blunt about his feelings, stating simply, "No creo en el amor" (I don't believe in love). For him, fixing problems means grand gestures like vacations, gifts, and getting intimate "Arriba del Rubicon" (on top of the Rubicon Jeep). It's a transactional kind of affection, but it has its own intense loyalty. He even says he engraved her name on his gun, which is a pretty wild way to show you care.
