Me pasé is a very common idiomatic phrase that literally translates to "I passed myself". It's the perfect way to say "I went too far," "I crossed the line," or "I overdid it."
In this song, Enrique Iglesias repeats this phrase to admit his big mistake. He sings, "Me pasé de copas" (I had too many drinks), which led him to cheat. Mastering this phrase is key to understanding the song's story of regret and is a great way to sound more like a native speaker.
Spanish pop star Enrique Iglesias teams up with Farruko for a track all about waking up in the wrong bed and scrambling for an excuse. The central confession is right there in the chorus: "Me pasé de copas / Me fui a dormir contigo / Y me desperté con otra" ("I had too many drinks / I went to sleep with you / And I woke up with someone else"). Instead of owning the mistake, the narrator points the finger at the bar menu. He insists that "La culpa fue del ron / De la cerveza y el Dom Pérignon" ("It was the fault of the rum / Of the beer and the Dom Pérignon"), throwing blame onto expensive vintage champagne, loud music, and hookah smoke before begging his partner not to throw the relationship away over one wild night out.
Farruko steps in with an equally shameless apology, dropping the Puerto Rican slang "mala mía" ("my bad") and trying to justify the mess by asking, "¿Qué culpa tengo yo que ella también sea bella?" ("How is it my fault that she is also gorgeous?"). It is cheeky, totally defensive, and funny because of how terrible his logic is. To top it off, he admits this is not even the first slip-up: "Hace más de un mes / Juré que era la última vez" ("More than a month ago / I swore it was the last time"). It is a party anthem wrapped inside the world's most chaotic hangover apology.
