Devorarte means "to devour you." While it literally refers to eating something completely, in this song, it's used metaphorically to express intense desire and passion.
Ivy Queen sings, "Y el solo pensarte Dan ganas de devorarte Parte por parte saborearte" (And just thinking about you makes me want to devour you, savor you part by part). This vivid imagery conveys a powerful, almost overwhelming longing and attraction, making it a very enticing and memorable word in the context of the song's seductive theme.
Ivy Queen's "Bye Bye" is all about that intense, forbidden attraction you just can't shake, even when you know you should. She's telling someone, "No me mires así / Porque se pueden dar cuenta" [Don't look at me like that / Because they might notice], making it clear they need to keep their distance in public. There's a history there, with "muchos recuerdos / Que por dentro arden" [many memories / That burn inside], but they have an agreement to stay "al margen" [on the sidelines].
But oh, the temptation! She admits, "Sabes que me tienta / Papacito yo si tengo el arte para seducir" [You know you tempt me / Daddy, I do have the art to seduce]. She even says, "Nadie me calienta como tu lo haces" [Nobody heats me up like you do], but quickly reminds herself, "No puede ser así / De pana lo siento / Hay que decirnos BYE BYE BYE" [It can't be like this / I'm truly sorry / We have to say BYE BYE BYE]. The song has a fun twist though: she warns that if he dares to challenge her and says he can handle her, "Sabe que me tiro y voy pa allá" [He knows I'll jump in and go there]. It's a playful yet firm declaration that while they should say goodbye, the pull is incredibly strong, and she's ready to break the rules if he gives her an opening!
