Masoquista translates to "masochist", a powerful and dramatic word to describe someone who finds pleasure in their own pain. It's a memorable term that you won't hear in every song.
In "Me Retiro," the singer feels like a masoquista for asking about his ex, knowing the answer will only hurt him more. It perfectly captures the self-destructive side of heartbreak, where one is drawn to the very thing causing the pain.
This song is for anyone who's ever had their heart completely shattered. The singer is going through a massive heartbreak and he is not handling it well at all. He admits he took things way too seriously, singing, "Dijiste que yo era tu vida y lo agarré bien literal" (You said I was your life and I took it literally). Now, everything feels wrong without his ex. The world is cold, so cold that "Julio parece diciembre" (July seems like December). He's drinking so much that even tequila has lost its kick, because as he says, "nada me sabe desde tu despedida" (nothing tastes like anything since you said goodbye).
He's taking this breakup to some pretty extreme places. He feels like his heart is locked and only she has the key. He's so over love that he gives a warning: "Aviso pa' Cupido, si lo veo, lo agarro a tiros" (A warning for Cupid, if I see him, I'll shoot him). It's so bad he's even confused his therapist! In the end, he's just done. He declares, "Ya quedó todo dicho, yo con esta me retiro" (Everything has been said, with this, I'm retiring), basically giving up on love completely.
