Mitómana translates to "mythomaniac" or "pathological liar." It's a strong and less common word that immediately grabs attention, suggesting a deep-seated issue rather than just a simple lie.
In the song, LIT killah uses it to describe someone who has become a compulsive liar, contrasting it with her past. This word adds a dramatic and accusatory tone, highlighting the artist's frustration and the perceived betrayal, making it a very impactful choice.
LIT killah's "No Hables Mal de Mí" [Don't Speak Ill of Me] is a super direct track about moving on from a past relationship, even when the ex is still causing drama. Our guy is over it, saying things like "No tengo ganas de escuchar esa canción" [I don't feel like listening to that song] and "No quiero darte flores" [I don't want to give you flowers]. He's lost his head trying to forget her, and he's not shy about saying he doesn't want to see her again because he heard she was talking smack behind his back.
He's pretty blunt about her character, calling her a "mitómana" [mythomaniac] and saying she was "resentida por mí" [resentful because of me]. He's found his peace, living life how he wants, and he's not bothered by her attempts to make him jealous. In fact, he says her bad-mouthing actually motivated him! He's definitely not holding back, and you can feel that icy resolve when he sings, "Me volví frío como el hielo" [I turned cold as ice].
