Piché is a fascinating word here because it's a colloquialism that can mean 'I pitched' (as in baseball) or, more commonly in this context, 'I ignored' or 'I dismissed'. It's a less common, more modern slang term.
In the song, Paloma Mami sings, "Por ti piché mis instintos" (For you, I ignored my instincts). This line powerfully conveys how she disregarded her inner voice and intuition for someone else, making piché a key word for understanding her regret and the song's emotional core.
Paloma Mami's "IGO" is all about that moment when you realize a relationship has gone sour, and it's mostly because of the other person's ego. She starts by saying, "Hace tiempo he estado sola" [I've been alone for a while], and then asks, "¿Cómo es que pasamos de amarno' a odiarno'?" [How did we go from loving each other to hating each other?]. It's a relatable feeling of looking back and wondering what happened to all that love.
She's pretty clear that the love turned into a "prisión" [prison], and the connection just isn't there anymore. Even though she admits, "Admito que te extraño" [I admit I miss you], she quickly adds, "Pero estás extraño" [But you're strange] and the blunt request, "No me hagas daño con ese ego" [Don't hurt me with that ego]. It's a powerful message about putting yourself first and not letting someone's ego mess with your head. You can really feel her frustration when she says, "Por ti piché mis instintos" [Because of you I ignored my instincts] and now, "No quiero amor si va con ego" [I don't want love if it comes with ego]. It's a great song for anyone who's ever had to deal with a partner's inflated ego!
