Encallar literally means "to run aground" or "to be stranded," often used in the context of a ship.
In "Pobre del Pobre," the word is used metaphorically to describe someone getting caught or trapped in a situation, specifically in romantic entanglements. The lyrics mention "las rumbas y encallar como solo a su presa," suggesting a predatory act where someone is lured into a situation and then trapped, much like a ship getting stuck. This makes it an interesting and less common word in song lyrics, adding a layer of intrigue to the narrative.
This song, "Pobre Del Pobre," is a really direct and intense message from someone who knows their friend is trying to steal their partner. The singer isn't just suspicious; they're certain, saying, "Sé que aprovechas mi ausencia hasta para dar con la forma de encontrarte con ella" (I know you take advantage of my absence to find a way to meet her).
It's all about betrayal, with the singer describing how their friend looks at their partner "con ganas y deseos de tenerla" (with desire and longing to have her). The singer even warns them, "Lo tuyo son cien perdidos pues ella ya sabe que debes y tu eres un tipo" (What you're doing is a hundred times lost because she already knows what you owe and you are a type). It's a blunt warning that their attempts are futile because the partner already sees through them. The singer feels a lot of sadness and disappointment, repeating, "No digas que soy perro viejo que cuando no he vuelto me causa tristeza" (Don't say I'm an old dog, that when I haven't returned it causes me sadness).
