Chicanero translates to "boaster" or "braggart". It's a less common, more colloquial term than simply saying someone is boastful, making it an interesting and memorable word.
In the song, the artist uses Chicanero to describe someone who boasts, perhaps about love or other things, but then contrasts it with deeper emotions and actions, like keeping a revolver for a duel. This word adds a layer of character and a hint of street wisdom to the lyrics, making it stand out.
Marc Segui and Barry B's "POR AMOR" is a super dramatic love song that's all about doing absolutely anything for the person you love. The lyrics are full of over-the-top promises and imagery, like building "un monumento de hielo encima del sol" [a monument of ice on top of the sun] or "una pirámide con un ascensor" [a pyramid with an elevator]. It's clear this love is so powerful it can even make "Fuego bajo el agua" [Fire under water]!
It's a really intense declaration, with lines like "He visto al Diablo pintar un corazón" [I've seen the Devil paint a heart] to show how crazy this love is. He even says he'd "cambio el destino / Para que así me aparezcas" [change destiny / So that you appear to me]. The singer admits to some self-destructive habits, like drinking and smoking a lot, and says everyone else seems ordinary compared to this one person. It's a fun, exaggerated take on being completely head-over-heels!
