Chepa is a fun Colombian slang word that means 'fluke' or a 'stroke of pure luck'. You'll often hear it in the phrase de chepa.
In the song, Feid mentions that jealous people say he's with his partner 'de chepa', implying he just got lucky and doesn't deserve her. This word offers a great peek into regional Spanish and the kind of casual language you'll hear in real conversations!
This song is a total flex from Feid, but it's also really sweet. He's basically telling his partner that now that he's successful, he wants to give her absolutely everything. He remembers when he wasn't famous, singing, "Cuando no tenía nada tú estabas ahí" [When I had nothing, you were there]. So now that he's getting paid, his first thought is her: "Cuando me llega un cheque siempre pienso en ti" [When I get a check, I always think of you]. He's so grateful that he can't believe his luck, saying he prayed for her and now "te tengo aquí desnuda, y ni me la creo a veces" [I have you here naked, and sometimes I can't even believe it].
He's not just talking, though. He's making big moves to prove his love and wealth, like when he says, "Cerré el restaurante pa' ti, bebé" [I closed the restaurant for you, baby]. He wants her to have access to all his money, telling her, "toma mis chavos, mis tarjetas" [take my cash, my cards]. It's his way of saying she deserves the world because she stuck by him. He wants a life with no stress or silly arguments, just him spoiling the person who was there from the start.
