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.
"Que Onda" drops you straight into a messy, secret hookup with someone who belongs in a completely different world. Fuerza Regida tells a story about getting with a "niña bien" [a well-off, high-class girl], but the vibe is far from classy. There is zero patience here: she could not even wait for the hotel and pulled him close right inside the "Merced" [Mercedes-Benz]. Instead of high-end shopping dates—he bluntly brags, "no la llevé a Chanel" [I didn't take her to Chanel]—the night runs on "tragos de Henny" [sips of Hennessy cognac], ordering pink cocaine ("el tusi") straight to the phone, and partying until 6:00 in the morning.
The thrill comes from how forbidden the whole thing is. He calls their bond "el amor de la calle" [street love], pointing out that she is sneaking around with a "cholo" [street-smart guy]. He even coaches her on how to hide it: "Maquíllate otra vez, no vayan a saber" [Put your makeup back on so they don't find out] and tells her to answer her regular guy with a calm "dile que todo bien" [tell him everything is fine]. Between deleting secret motel photos and ignoring their rings, his big question is simple: "¿Qué tal si por la noche apagamos los dos el cel?" [How about tonight we both turn off our phones?]. It is fast, reckless, and completely unbothered by the rules.
