Retuerce comes from the Spanish verb 'retorcer', meaning to writhe, twist, or contort. It's a vivid, almost violent word that paints a strong physical image of struggle or pain.
In the song, the line "Otra víctima inocente que se retuerce entre tus dientes" (another innocent victim who writhes between your teeth) uses the word to create a dark, predatory image, as if the person being sung about devours everyone who gets too close.
Caramelos de Cianuro brings us a darkly humorous and dramatic tale of a love gone wrong in "Infierno VIP." The singer feels like a "tenorio en el purgatorio" [Don Juan in purgatory] and an "alma en pena sin velorio" [tormented soul without a wake] ever since meeting this person. It's clear they've been utterly consumed, feeling "muerto desde que te vi" [dead since I saw you], trapped in the "infierno VIP" [VIP hell] of this relationship.
Our narrator describes themselves as "otra víctima inocente que se retuerce entre tus dientes" [another innocent victim writhing between your teeth], leaving a "mancha carmesí" [crimson stain] on the floor of this exclusive hell. The frustration is palpable as they ask, "Si para bailar hacen falta dos ¿Por qué te fuiste sin decir adiós?" [If it takes two to dance, why did you leave without saying goodbye?]. There's a sense of betrayal and a grudging "simpatía por la Diabla" [sympathy for the She-Devil], who is described with "falsos ojos, falso pelo, falso azul de un falso cielo" [false eyes, false hair, false blue of a false sky]. The song ends with a repeated, bitter curse, "Maldito el día en que te vi" [Cursed be the day I saw you], cementing the idea that this encounter was a one-way ticket to a very exclusive, very painful, VIP hell.
