Estribo literally means "stirrup," the footrest on a saddle. However, in this song, it's used in the common Spanish idiom "la del estribo," which refers to the very last drink before leaving a place, often a bar or cantina.
This phrase perfectly captures the melancholic atmosphere of the song, where the singer is drowning his sorrows and asking for one more drink to prolong his stay and his memories. It's an interesting cultural idiom that adds depth to the lyrics.
This song, "Tu Recuerdo y Yo" by Leonel Garcia featuring Maria Toledo, is a classic tale of heartbreak and trying to forget someone who did you wrong. Our singer is in a cantina, listening to a song they requested, and drinking tequila. They admit, "Yo sé que tu recuerdo es mi desgracia" [I know your memory is my misfortune], and they're there just to remember how bitter things are when "hay una mujer que paga mal" [there's a woman who pays badly].
It's a relatable feeling, right? The song asks, "Quién no sabe en esta vida la traición tan conocida que nos deja un mal amor?" [Who doesn't know in this life the well-known betrayal that a bad love leaves us?]. And who hasn't ended up in a cantina, demanding tequila and a song to drown their sorrows? By the end, they're on their last drink, "la del estribo" [the stirrup cup], and they're not even sure if they have faith anymore. All they want is for the musicians to play "la que se fue" [the one that left] again. It's a raw, honest look at dealing with a broken heart.
