Desvare comes from the verb desvarar, which literally means to refloat a boat that has run aground. In Colombian slang, it's commonly used to mean 'to get someone out of a jam' or 'to help someone out of a difficult situation'.
In the song, the singer repeatedly promises to pay back a debt, even making outlandish excuses. He uses desvare to reassure his friend, saying, "Voy a hacer el sacrificio / Para que usted se desvare" (I'm going to make the sacrifice / So that you get out of trouble), implying he'll find a way to help his friend, despite his own financial woes.
“La Promesa” is a humorous ode to New Year’s resolutions, Latino style. Over a lively vallenato–pop beat, Andrés Cepeda and Fonseca list every goal we swear we will achieve when the calendar flips: quit smoking, hit the gym, save money, learn English, even buy that flashy red Lamborghini. At the same time, they poke fun at how easily those dreams slip away. The singers keep reassuring a long-suffering friend, compadre, téngame fe, promising that the debt will be paid and life will finally straighten out—if not this year, then surely the next.
Beneath the playful jokes lies a relatable message about optimism and perseverance. Time may fly, plans may fall apart, but the spirit of “otro mejor llegará” (a better year will come) keeps everyone dancing and dreaming. “La Promesa” reminds us that hope is renewable; we can always make fresh promises, sing them out loud, and try again with a smile.
