Carajo is a versatile and strong Spanish expletive, often translated as "damn it" or "hell". While it can be vulgar, in this context, it's used to express intense dismissal or defiance.
In the lyrics, "Yo voy por lo mío pa'l carajo vete" translates to "I'm going for what's mine, go to hell/damn it". It's a powerful way for the singer to tell his ex to get lost and that he's moving on, making it a memorable and emotionally charged word.
This song is one of the most savage breakup anthems you'll ever hear. Pipe Bueno and Maluma team up to tell an ex that not only are they over her, but they're thriving while she's supposedly falling apart. The singer starts by saying, "Gracias a Dios te fuiste" [Thank God you left] and that he's finally calm now that their constant fighting is over. The whole mood is relief and a little bit of gloating.
The chorus is where it gets really spicy. They paint a picture of her coping badly with the split, singing, "mientras tú te matas con tequila / Fumando en la ventana noche y día" [while you kill yourself with tequila / Smoking in the window night and day]. They rub it in by asking, "¿Cómo putas me olvidas?" [How the f*** do you forget me?], after reminding her of all the good times they had. Maluma's verse is even more direct, claiming he saw her at a party looking a mess: "Estabas borracha y oliendo a mari" [You were drunk and smelling of weed]. He ends with the classic cold line, "Si sabes contar, no cuentes conmigo" [If you know how to count, don't count on me]. It's a confident, almost arrogant, song about winning the breakup.
