Borregos literally translates to "sheep" or "lambs." While it can refer to the animal, in Spanish, it's often used metaphorically to describe people who blindly follow others without thinking for themselves.
In this song, Dani Martin uses it to criticize those who conform to societal expectations, singing, "Como borregos, como borregas" (Like sheep, like sheep). It's a vivid and somewhat provocative word that highlights the song's theme of rebellion and individuality.
The song opens in somebody else's voice, reading out a life plan: “Tienes que ser perfecto y convertirte en alguien de provecho” (You have to be perfect and become someone useful), “Debes hacer una carrera convencional y ser ejemplo” (You must pursue a conventional career and be an example). Dani Martín lets it run for four lines and then answers with a question — “¿Cuántas cadenas, cuántas cadenas?” (How many chains, how many chains?) — aimed at people he calls “Amargaditos como almas en penas” (Bitter people like souls in torment), living “Como borregos, como borregas” (Like sheep, like sheep).
His whole reply is the five words the chorus repeats until they stop sounding like a slogan: “Lo que me dé la gana” (Whatever I want). What he actually wants turns out to be small and mostly tender — “Quiero drogarme con tu saliva” (I want to get high with your saliva), “Quiero luchar por las causas perdidas” (I want to fight for lost causes), “Quiero robar las flores que están muriendo en el ataúd” (I want to steal the flowers dying in the coffin) so he can hand her the bouquet. The rude images earlier in the verse are there to draw the judgement, and when it arrives — “Le faltan modales y educación” (He lacks manners and education) — he answers it plainly: “Mírame a la cara” (Look me in the face), “La vida me lo enseñó” (Life taught it to me). The last verse drops the provocation entirely and ends on “Voy a volver a coger tu carita” (I'm going to hold your sweet face again).
