Despistada is a fantastic adjective that means "clueless," "absent-minded," or "distracted." It's used to describe someone who isn't paying attention to what's really happening around them.
In the song, Cazzu sings directly to the new girlfriend, calling her despistada for worrying about the wrong person. She warns her, "Tienes tu enemigo durmiendo en tu cama" (You have your enemy sleeping in your bed), implying the real threat is her own boyfriend, not Cazzu.
Argentine artist Cazzu serves up a direct dose of karma in this reggaeton track, talking straight to the woman who took her ex. She starts off with a classic proverb: “La que nada debe, nada teme” (She who owes nothing fears nothing) and reminds her that “robado se va lo que robado viene” (what comes stolen leaves stolen). In plain terms, how you get them is how you lose them. Instead of being jealous, Cazzu explains that she has zero interest in taking him back—she barely even looks his way when he reaches out.
The real punchline of the track is where the actual threat lies. Cazzu points out: “No soy tu enemiga / Tienes tu enemigo durmiendo en tu cama” (I'm not your enemy / You have your enemy sleeping in your bed). She tells the new girlfriend that she is “muy despistada” (completely clueless) for guarding against the wrong woman. She does not wish bad things on her, but promises that history will repeat itself: “él te va a engañar con otra” (he is going to cheat on you with someone else). When that happens, she will remember how she used to laugh back when Cazzu was the one in her shoes.
