I don't like to shit in my own front yard
This is your town, big or small. You have a rep to maintain. You gotta hold your head high around your stomping grounds. If your gonna act slutty or a fool... you take it else where! Don't shit in your own front yard, people will see you. Go across town, and shit in someone else's yard :)
Friend: "Why don't you just go home with him?" You: "I don't like to shit in my own front yard, if you know what I mean."
