Farsante translates to "impostor" or "fake." It's a strong, evocative word that goes beyond simple deception, implying a deliberate act of pretending to be something one is not.
In "Doliendo Bastante," the singer repeatedly calls his ex-lover a "farsante" because she disguised herself as someone she wasn't, ultimately hurting him deeply. This word perfectly captures the betrayal and the feeling of being deceived by someone who presented a false image.
Carín León opens by handing his ex the strangest compliment in the song: "Tú me mataste y yo te guardé el duelo" (You killed me and I mourned you). She did the killing, and he still did the grieving. From there it is a list of what he misses, and he is honest that most of it is physical: "Lo bueno que era quitarnos la ropa" (How good it was to take off our clothes). The tequila gets a mention too, though it backfires. "Dicen que con tequila duele menos / Pero también me recuerda lo bueno" (They say that with tequila it hurts less / But it also reminds me of the good).
The chorus turns bitter and a little petty, which is the best thing about it. "El premio a la más mentirosa te lo ganaste" (You won the award for the biggest liar) is delivered like an actual awards ceremony. What stings is not the lying at all: "Lo que duele es que no hiciste nada pa' quedarte" (What hurts is that you didn't do anything to stay). Listen to the end of the first chorus, where the line breaks off mid-word on "Una farsante, me está doliendo bastan-" (A fake, it's hurting me a lot-). He cannot get through saying how much it hurts. By the last verse the anger has drained out and all that is left is "Y yo te extraño comoquiera" (And I miss you anyway).
