Traficar literally means "to traffic" or "to deal" (as in, to deal drugs or illegal goods). It's a provocative and attention-grabbing word that immediately suggests a darker, more rebellious theme.
In the song, Melendi uses it with a double meaning. While it hints at illicit activities, he also uses it metaphorically to describe a return to a more chaotic, perhaps less conventional, way of life after being tired of a mundane job. He sings "Vuelvo a traficar" (I'm going back to trafficking), implying a return to a life of excitement and risk, even if it's not literally about drug dealing. This dual interpretation makes the word particularly intriguing and memorable.
"Vuelvo a Traficar" is Melendi's tongue-in-cheek anthem about quitting a dead-end job and diving back into nightlife. The narrator is done with a "curro" (job) that gives him nothing anymore, so he walks away and declares his new life has begun.
"Traficar" (to traffic or deal) is used as a wink, not literally. It paints the street corners, bars and late nights of city life as his new hustle: drowning his sorrows, maxing out cards, climbing stairs at 4am, dodging breathalyzer checks. It is really about people chasing a good time rather than actual drugs, using the language of dealing to describe escaping a grind that stopped paying off emotionally.
The chorus leans into a simple, defiant philosophy: work can dignify you, or it can't, but life is too short and too beautiful to lose to a job that drains you. It's a light, danceable rejection of burnout dressed up as a crime story.
