Vicio literally translates to "vice" or "addiction." While it can refer to a bad habit, in a romantic context, it's used to express an intense, almost uncontrollable need or craving for someone.
In "Primera Cita," CNCO sings, "Eres mi aire, eres mi agua, eres mi vicio" (You are my air, you are my water, you are my addiction). This powerful metaphor highlights how essential and captivating the person is to the singer, making it a memorable and passionate declaration of love.
Have you ever met someone and instantly lost your mind? That is the exact rush CNCO brings in "Primera Cita" (First Date). Right from the opening lines, he is head over heels, comparing this new crush to essential elements: "Eres mi aire, eres mi agua, eres mi vicio" ("You are my air, you are my water, you are my vice"). Calling someone a "vice" alongside basic survival needs like air and water is dramatic, but that is the charm of an intense crush. The singer is totally defenseless against it, shrugging his shoulders with "¿Qué le hago yo? El amor es así" ("What can I do? Love is like this").
There is a great Spanish idiom here worth learning: "Hoy mi alma se viste de etiqueta" ("Today my soul dresses in black tie"). Vestirse de etiqueta literally means dressing up in formal wear or a tuxedo, so saying his soul is wearing formal attire means he is putting on his absolute best self just hoping she comes back to him. Between promises of kisses for breakfast ("besos para desayunar") and promising to color in her gray days with melodies, he leaves his front door wide open ("Entra sin tocar la puerta" / "Come in without knocking"). It is sweet, playful, and completely shameless about falling in love on day one.
