Pacas is a popular slang term for "bundles" or "stacks," specifically referring to large amounts of cash. The word is an anglicism, likely derived from the English word "packs."
In the lyric "Que sigan llegando las pacas" (Let the stacks keep coming), the artist celebrates wealth and success, a common theme in this genre of music. Learning this word gives you a key piece of slang to understand the culture behind today's biggest hits from Mexico.
Fuerza Regida's "Que Onda" is all about a secret, intense hookup between two people from different worlds. The singer describes himself as a "cholo" and calls her a "niña bien" [good girl], suggesting she comes from a more proper or wealthy background. Their connection is purely physical and happens in secret, away from judging eyes. He's not taking her on fancy shopping trips—he says, "Pedí el tusi por cel, no la lleve a Chanel" [I ordered drugs on the phone, I didn't take her to Chanel]. It's a raw, unfiltered encounter.
The whole song is built around this idea of a hidden, wild side. They don't even make it to the hotel, getting together "arriba del Merced" [on top of the Mercedes]. He asks her to hide the evidence of their time together: "Maquíllate otra vez, no vayan a saber" [Put on your makeup again, so they don't know]. The central question of the song is a simple invitation to escape their normal lives for a night: "¿Qué tal si por la noche apagamos los dos el cel?" [What if tonight we both turn off our phones?]. He sums up the whole vibe himself by calling it "el amor de la calle" [street love].
