Apendejé comes from the informal verb apendejarse, which means to act foolishly or to mess up. It's a colloquial and somewhat strong expression, making it memorable and impactful.
In the song, Miky Woodz sings, "Me volví loco por ti, creo que me apendejé" (I went crazy for you, I think I messed up). He uses this word to express regret and self-blame for his actions or decisions made out of love, highlighting a moment of vulnerability and realization.
In "No Fue Así," which translates to "It Wasn't Like That," Puerto Rican rapper Miky Woodz tells the story of a devastating breakup. He feels like he bet everything on the relationship and ended up in ruins, so heartbroken that he doesn't even want to leave his house. He admits he was a destructive force in his ex's life, comparing himself to "Hurricane Katrina," but he deeply misses the simple, intimate moments they shared, like seeing her in the kitchen or her makeup in the bathroom. Without her, he feels his self-worth is "zero."
The singer pushes back against the reasons for their split. He feels she made a quick decision based on rumors, thinking he was just out partying when that "wasn't the case." He laments that she never gave him a chance to explain his side of the story. He reflects on the sacrifices he made for her, like distancing himself from friends and even quitting smoking weed. Now, he's lost all faith in love and commitment, feeling like love has knocked him to the ground. The song is a raw expression of heartbreak, regret, and the feeling of being misunderstood after a relationship ends.
