Actually saying “Curse you” might be a problem. Quoting where someone else says that – not so much. The Bible (one of Paul’s epistles, I think) does tell us to “bless, and do not curse.”
That said, we recently traveled to Orlando and back (no, we weren’t visiting the Mouse), and I saw a lot of billboards for adult stores and strip joints. I did pray that the Lord would curse those establishments in such a way that their organizers and employees would be led into the truth about the errors of their ways.
