Pata suelta is an idiomatic expression that literally translates to "loose paw" or "loose foot". It's a colorful and memorable phrase that you won't hear in every song.
In the context of the song, it means being "footloose" or "on the loose" – living a life of freedom, without responsibilities or ties. The lyrics state, "Por andar de pata suelta dando doble vuelo a la vida" (For being footloose, living life to the fullest), indicating a carefree and adventurous lifestyle. This phrase captures the essence of the song's narrative about a life lived outside conventional norms.
Beto Quintanilla's "Mina De Hierba" tells the story of someone who learned a lot about life, both good and bad, growing up in the mountains. He says, "hacia arriba de la Sierra me crié con puros nopales y flores de palma china" [up in the Sierra, I grew up with only cacti and Chinese palm flowers]. He even dreamed of making money from pure goat's milk!
Things take a turn when he finds a patch of "hierba" [weed]. He sells it in town, and his father's friends quickly buy it. This leads to wealth, and he sells his "mina de hierba" [weed mine]. Now, he's on the run, saying, "ahora me buscan las leyes pero hacen que no me encuentran" [now the law looks for me but they pretend not to find me]. He keeps his money buried and travels to the United States, always remembering he's "purito mexicano" [pure Mexican].
