Diabética literally means "diabetic". It's a highly unusual and striking word to find in a love song, making it instantly memorable.
In the lyrics, Don Omar sings, "Otros amores del pasado me han dejado diabética y no puedo ser dulce contigo" (Other past loves have left me diabetic, and I can't be sweet with you). He uses this metaphor to express how past heartbreaks have made him emotionally guarded and unable to be tender or vulnerable in a new relationship. This creative and unexpected use of the word adds a unique layer of meaning to the song.
Ever swear off dating completely, only for someone to show up and ruin all your plans? That is the exact mess Puerto Rican star Don Omar and Natti Natasha run into here. Both singers open with regrets: "Juré que no volvería a sucederme de nuevo" ("I swore it wouldn't happen to me again"). They blame Cupid for trapping them in his silly games. Natti drops one of the wildest complaints about past heartbreak you will ever hear: "Otros amores del pasado me han dejado diabética y no puedo ser dulce contigo" ("Other past loves have left me diabetic, and I can't be sweet with you"). She literally claims past romance gave her medical sweetness overload, so she refuses to play nice! She is also terrified he might sell her a fantasy ("vendan un sueño", meaning to spin false promises) and sneak back to his "dueña" (his "owner" or main girlfriend) tomorrow.
Don Omar hears her loud and clear, but he cannot help himself. He admits he used to wander the world aimlessly ("caminaba solo en el mundo, sin rumbo"), yet the way she dances and kisses wipes away his defenses. Notice how he borrows the Jamaican patois slang "gyal" (girl) alongside English phrases like "You drive me crazy mama". It feels like a late-night argument on the dance floor between two people who have been burned before, trying desperately not to fall again while their bodies do the exact opposite.
