Really, is my world that different from yours?

Please tell me that there are other people out there who are familiar with the phrase "give him/her/them down the road". In our house, Kate and I are the only ones who have ever heard it. I used it the other day when talking about my cheaters, and no one knew what the heck I meant. I asked Jeff, and he'd never heard the phrase either. Is it only a Southern thing? What is the origin of it? I tried looking for info online but without success. If you know, let me know. And if you've heard or used the phrase before, let me know that too. I'm beginning to think I might live in an alternate universe from everyone else.
