What is 10 Tile Rule?
phrase- simply means that if you're ever forced to go somewhere in public with your parents (the local mall for example), and you don't want to be seen in this humiliating situation, you walk 10 tiles ahead of your parents, nobody will ever notice that you're with them. The whole thing goes out the window if they scream your name out across the mall, but the entire situation can be avoided completely if you just bring your cell phone and they allow you to leave their watchful eyes.
John: I have to go to the mall with my parents, and for some reason they said I can't leave their sight.
Joe: No sweat man. All you have to do is use the 10 tile rule.
