Spanish Language(s)

Today I was talking to a puerto-rican girl, and we were talking in Spanish. She didn't quite believe me at first when I told her that I could speak Spanish. We chatted a little bit, and then she said something that I couldn't recognize at all (I couldn't even remember it, sadly). I told her that I did not understand, and her response was something along the lines of "that's because I'm speaking Puerto Rican."
