Desplumar literally means "to pluck feathers from a bird." It's a vivid and somewhat aggressive verb that isn't commonly found in everyday song lyrics.
In "Caníbal," iLe uses it metaphorically in the line "El corazón desplumado" (The heart plucked/fleeced). This suggests a feeling of being stripped bare, vulnerable, or even exploited emotionally, adding a raw and intense layer to the song's themes of self-discovery and transformation.
iLe's "Caníbal" turns heartbreak into an act of self-surgery. She opens numb, confessing "Se estrujan mis sentidos" [my senses are crushed] and "No puedo despertar" [I can not wake up], describing a body "ya curtido" [already hardened] that still wants to try again. To move forward she has to "Acuchillar mis miedos" [stab my fears] and "Desenchufar todos mis dedos" [unplug all my fingers], cutting loose the desires that keep her stuck.
The chorus circles back to the same fall every time: "(Caí)" [I fell], "Estando arriba" [being up], "Y era mentira" [and it was a lie] — the high of love collapsing into a lie. In the bridge she pushes the metaphor further, turning her own heartbreak into cannibalism: "Un cuerpo fue devorado" [a body was devoured], "El corazón desplumado" [the plucked heart], "En mí estaba latiendo" [was beating inside me]. She survives by consuming and rebuilding herself, "Fui descociendo mi ser" [I was unstitching my being] to find out who is left underneath.
