Mentirosa translates to "liar" in English. It's a direct and emotionally charged word that immediately grabs attention.
In this song, the singer repeatedly calls out his ex-lover as a "mentirosa" and "embustera" (another word for liar), highlighting her deceit and the pain it caused him. This word is central to the song's theme of betrayal and heartbreak, making it highly impactful and memorable.
"Mentirosa" is Elefante's kiss-off to a lover who lied one time too many. The singer opens resigned rather than furious — "Qué le vamos a hacer" ["What can we do?"], "Si la vida es así" ["If life's like that"] — before admitting he staked everything on a romance built on nothing: "Le aposté todo a tus besos" ["I bet everything on your kisses"]. The chorus turns that resignation into an accusation, stacking "Mentirosa, traicionera" ["Liar, betrayer"] against "Mentirosa, embustera" ["Liar, deceiver"] as he tallies what he gave up: "Y yo que daba por ti la vida entera" ["And I who'd give my whole life for you"].
By the final chorus he's done asking for explanations — "Yo contigo no regreso aunque me muera, no no" ["I'm not coming back to you even if I die, no no"]. It reads less like a plea than a door closing: "Vete por donde llegaste" ["Go back where you came from"], set to the band's rock-pop drive so the heartbreak plays out loud instead of quiet.
