This is basically for anybody to implement this when its time to punch in that number that you just scored. Read the number back to the girl and when you do say it wrong or fuck up the order of the numbers and if she corrects you then you know you most likely don't have a fake number. You can also sort of gauge her interest level in you if she cared enough to correct you and not just let you have a wrong number. And That's it, stay motivated everyone.
