If you visit Florida now, you will see a lot of Florida residents who are cross-eyed. I have not yet visited Florida. I know that from Mr. Kun Jiang, a very famous Chinese cross-talker. He told me in a TV programm. According to him, a lot of Florida residents got cross-eyed because they spent so much time in scrutinizing the presidential election ballots.
Please be careful in using this word if the person you are taling to is really cross-eyed.
