Acorralado translates to "cornered" or "trapped." It's a vivid and somewhat dramatic word that paints a strong picture of feeling stuck and without escape.
In the context of the song, Yeison Jiménez uses it to describe the intense and painful feeling of being deeply in love, yet simultaneously feeling trapped by the emotions and the potential for heartbreak. He sings, "Y cómo duele, cómo duele, sentirse acorralado" (And how it hurts, how it hurts, to feel cornered), highlighting the suffocating aspect of a difficult romantic situation.
Yeison Jiménez's "Cómo Duele" is all about the pain of love and betrayal. He starts by talking about how wonderful it is to meet someone new and feel your heart wanting to burst out, but then quickly shifts to the harsh reality: "Pero cuando uno menos piensa lo traicionan" [But when you least expect it, they betray you]. It's a blunt look at how quickly that joy can turn into suffering when you're cheated on.
The chorus really drives home the feeling, repeating "Duele, duele, duele estar enamorado" [It hurts, it hurts, it hurts to be in love] and how much it hurts to feel cornered or betrayed by Cupid's arrow. He even says, "Lastimosamente, es la realidad" [Unfortunately, it's the reality] and that anyone who falls in love is bound to cry. By the end, he's decided he's not going to beg anymore, and if love comes again, he'll take advantage of it, but "Sin poner el corazón" [Without putting his heart into it]. It's a classic tale of love gone wrong, with a powerful message about protecting yourself from future heartbreak.
