Explícitas translates to "explicit". It's a bold and direct word that immediately grabs attention, especially in a pop song.
Becky G uses it to describe "haciendo cosas explícitas" (doing explicit things), hinting at the intimate and passionate nature of the relationship. This word choice adds a layer of intrigue and suggests a mature, confident tone, making it very enticing for listeners.
Becky G builds this one around a single admission: she has stopped deciding. "Somos un clásico" (We're a classic), she shrugs, "Siempre terminamos así" (We always end up like this). The title is the excuse and the diagnosis at once. Whatever pulls her back to this person runs without her, which is why the best line here is also the most resigned: "Imposible terminar / Lo que siempre comienza" (Impossible to finish what always begins).
The verses stay in her head rather than in a room. "Te veo siempre que sueño o se apaga la luz" (I see you whenever I dream or the light goes out) puts the whole affair somewhere private, and "Siento tus manos / Tocar mi cuerpo cuando me piensas" (I feel your hands touch my body when you think of me) makes the distance beside the point. She flips between Spanish and English the way the song flips between wanting and admitting it, and the English side is mostly one blunt phrase repeated until it sounds like a heartbeat: "I want it, I want it." By the time she gets to "Foreva puesta pa' ti" (Forever down for you), the argument is over.
