Disfraz means 'disguise' or 'costume'. It's a vivid and slightly dramatic word that isn't in every song, making it stand out.
Jay Wheeler sings, "Toda las promesas tuyas solo fueron un disfraz" (All your promises were just a disguise). He uses it to express a deep sense of betrayal, revealing that his ex's sweet words and promises were nothing but a mask hiding her true intentions. It’s a powerful metaphor for deception in a relationship.
Jay Wheeler brings his smooth Puerto Rican reggaeton style to an absolute breakup anthem, but do not expect him to beg for his ex back here. Right off the bat, he drops the polite act. He tells his former partner, "No fuiste mala, pero no fuiste suficiente" ("You weren't bad, but you weren't enough"), and calls them out for talking trash behind his back. The main takeaway is repeated like a victory lap throughout the chorus: "Aprendí a ser feliz sin ti" ("I learned to be happy without you"). He bluntly admits that being in that relationship felt sickening, and dealing with her drama ruined his ability to trust anyone new.
What makes this track fun is how brutally honest Jay Wheeler gets when describing his single life. He uses real Puerto Rican street slang to hammer home that he is completely finished. When he sings "yo te boté" ("I dumped you" or literally "I threw you in the trash"), he is using a common island idiom for casting someone aside like garbage. He is so fed up with love that he declares, "A estar soltero me acostumbré" ("I got used to being single"). To top it off, he admits he smoked so much trying to cope that his lighter ran out of gas ("el lighter se quedó sin gas") before sleeping with someone else to close the chapter for good. It is petty, direct, and completely refreshing.
