Desliz usually means a slip-up or lapse, often an unintentional mistake. In the song, MC Davo says he will treat the past relationship como un desliz, reducing the entire romance to a mistake he can move on from, which gives the word a sharp and memorable emotional impact.
MC Davo and Calibre 50 turn a breakup into a sharp question: “¿Quién te crees?” [Who do you think you are?] The ex-partner no longer gets to control his mood or decide whether he is happy. He admits that forgetting her is difficult, but draws a firm line: “Fuiste una vez mi gran amor, pero nadie es indispensable” [You were once my great love, but nobody is indispensable]. He wishes her well, while also saying that the relationship ended because she failed him and that the love they had cannot simply be found again. The message is hurt, proud, and determined to move on.
The rap verse adds a more sarcastic edge. Their relationship went from something beautiful to “un dolor de cabeza” [a headache], while social media turns the breakup into a story other people believe. He jokes that she uses fake accounts to play detective, calls other women “mamis” [an informal slang word for attractive women], and says, “nah, ni quien te pele” [no way, nobody is paying attention to you]. The line “La relación es de dos, no es de uno” [A relationship is made of two people, not one] sums up his complaint: he cannot carry all the responsibility alone. It is a lively meeting of Mexican rap and regional music, with wounded pride quickly becoming self-respect.
