Maquinando comes from the word máquina (machine). Its literal meaning is 'machining,' but in slang, it means 'plotting' or 'scheming'—as if the gears are turning in your head while you make a plan.
In the song, Jey One sings "Maquinando pa' bregarte" (Plotting on how to get with you). He uses this cool, evocative word to describe the intense mental game of flirtation, where he's planning his next move to win the girl's attention. It's a perfect word for a moment full of suspense and anticipation.
In "Onana", Dominican dembow artist Jey One spots someone across the room and catches all the secret signals she is throwing his way. The whole hook hinges on a risky, sneaky vibe: "Oye, yo siento que tú me dices algo / Pero tu marío' te está mirando" ("Listen, I feel like you're telling me something / But your husband is watching you"). She is pretending nothing is happening ("Tú lo estaba disimulando" ["You were playing it off"]), but he sees right through the poker face. He watches her get nervous and quick on her feet the moment he pulls up on the corner dressed to kill, boasting that he looks "peluche, nuevecito de vitrina" ("fluffy, brand new out of the display case").
Jey One loves the tension, especially her bold attitude. He admits, "tú me gusta' pila con tu cara de agresiva" ("I like you a lot with your aggressive face"). In Dominican street slang, pila means "a ton" or "a lot." He calls her out for having a drink, staring him down, and silently scheming: "Me comiste con los ojos, mami" ("You ate me up with your eyes, mami"). Things turn blunt and dangerous when he talks about "maquinando pa' bregarte" ("plotting to deal with you") alongside a loaded gun clip ("el peine llenó de la negra"). It is loud, chaotic, and completely focused on the rush of flirting right in front of someone's partner.
