Me rifé is a powerful slang expression, especially common in Mexico, that comes from the verb rifarse. It means to voluntarily take on a big risk, excel at a difficult task, or put yourself on the line for something.
It carries a strong sense of courage and succeeding against the odds. In the song, the line "Nunca fue fácil pero me rifé" translates to "It was never easy but I stepped up and took the risk". This phrase perfectly captures the song's story of overcoming hardship to achieve success, making it a very cool and inspiring expression to learn.
Fuerza Regida's "FDVP" is a story about coming up from nothing. The singer looks back on his tough past, saying, "No se me olvida cómo la perrié / Nada fue fácil, cómo batallé" (I don't forget how I struggled / Nothing was easy, how I battled). His motivation was simple: to provide for his family. He's very direct about how he did it, admitting he had to sin and work in illegal business just to eat: "Chambeo en lo malo pa' poder comer / Por mi familia fue que me enredé" (I work in bad things to be able to eat / It was for my family that I got tangled up).
Now, things are different. He has achieved the four things he prayed for, which also make up the song's title: "Fama, dinero, viejas y poder" (Fame, money, women, and power). He also notes how people treat him differently now that he's rich. Despite his new status, he insists he's the same person he's always been. The lyrics are very blunt about his work, mentioning sending kilos to the United States: "Ya contesté, kilos mandé / Si no el billete del gabacho para qué" (I already answered, I sent kilos / If not, what's the money from the USA for?).
