Deslumbras is the 'you' form of the verb deslumbrar, which literally means 'to dazzle' or 'to blind with a bright light'. It’s a beautiful and poetic word perfect for a grand compliment.
In the song, Becky G uses it to describe someone so charismatic and good-looking that they outshine everyone else in the room. She sings, "Si voy contigo deslumbras en los lugares" (When I'm with you, you dazzle everywhere), highlighting her partner's powerfully captivating presence.
Te Quiero Besar brings together Mexican-American group Fuerza Regida and Becky G for a fiery, back-and-forth corrido tumbado about a couple who cannot stop clashing, yet refuse to walk away from each other. Right from the start, the blame game kicks off. Fuerza Regida calls out an emotionally distant partner with lines like "Tú no eres cariñosa / Te mando flores y respondes otra cosa" ("You are not affectionate / I send you flowers and you reply with something else") and complains that she acts cold and tries to buy her way out of trouble ("Con tu dinero todo quieres arreglar" ["With your money you want to fix everything"]). Becky G throws it right back, admitting he is far from ideal but too attractive to resist: "Tú no eres perfecto / Y lo malo es que a mí me gustan tus defectos" ("You are not perfect / And the bad thing is that I like your flaws").
Despite the petty fights and jealousy—where she warns "No quiero ver nadie / Que se te arrime cuando pases a la calle" ("I don't want to see anyone / Getting close to you when you walk down the street")—they always choose physical passion over lingering grudges. When Becky sings "esta noche nos comemos" ("tonight we eat each other up"), it is a common Spanish idiom meaning to make out or hook up intensely. In the end, cruising around ("vamos a manejar" ["let's go for a drive"]), drinking champagne, and sealing everything with a kiss ("Te quiero besar, ya no importa nada" ["I want to kiss you, nothing else matters"]) beats staying mad. They know they are toxic together, but they simply do not care.
