Encajoso is a fascinating word that doesn't have a direct, single-word translation in English. It describes someone who is presumptuous, takes advantage of others, or overstays their welcome.
In the context of the song, the singer thanks Jesús Malverde for his blessings and states, "Por no ser tan encajoso, gracias por lo que me has dado" (So as not to be so presumptuous/exploitative, thank you for what you have given me). This implies a sense of humility and gratitude, acknowledging that he doesn't want to be seen as someone who constantly asks for favors without showing appreciation.
This song is a corrido, a traditional Mexican narrative ballad, performed live. It's a powerful song of devotion to a folk saint named Jesús Malverde. The singer expresses deep faith, explaining that he prays to Malverde with fervor and carries his picture in his wallet for good luck and protection. The lyrics describe a pilgrimage to Malverde's chapel in Culiacán, a city in Sinaloa, Mexico, to give thanks for good fortune.
Throughout the song, the singer shows his gratitude for the saint's help, especially in his business dealings or "tratos." He keeps a candle lit in Malverde's honor and trusts him completely, leaving his fate in the saint's hands. Rather than asking for riches, he asks for humility. The song ends with a promise to return the following year, thanking Malverde for being so miraculous and for all the blessings he has received.
