Parceros is a Colombian slang term for 'buddies' or 'close friends'. It's a more informal and regional word than common terms like 'amigos'.
In the song, the artist uses parceros to highlight the hypocrisy of people who only claim to be his friends when he's doing well, contrasting them with those who truly supported him during tough times. This word adds a touch of authenticity and cultural flavor to the lyrics.
This song is Juan Vargas looking straight at the people who ignored him when he was struggling and suddenly want to be close now that he has money. He remembers very clearly how “cuando yo anduve en la mala” [when I was doing badly] people laughed at him and “hasta me dieron la espalda” [they even turned their backs on me]. Now that “las cosas van cambiando” [things are changing] and life is treating him better, everyone wants to go out with him and pretend they were always his friends. That fake “we’ve always been tight” attitude is exactly what he’s calling out.
At the same time, he thanks God for the tough times: “Él me apretó la soga, pero no me ahorcó” [He tightened the rope on me, but He didn’t hang me]. It’s his way of saying the struggle was real, but it didn’t kill him. The song also draws a hard line about who really matters. When you are “en la mala” [in a bad moment], “solo quedarán a tu lado los familiares” [only your relatives will stay by your side], like “la vieja que te parió, el que te crió” [the woman who gave birth to you, the one who raised you]. Everyone else, he keeps at a distance: “Conmigo comentan los que a mi lado aguantaron” [Only those who endured by my side can talk with me]. It’s a proud, slightly sarcastic song about remembering who was real when he had nothing and refusing to let fake friends rewrite the past now that there’s “billete” [cash] in his life.
