Manchester is when a friend says somthing they will do and if you quickly say manchester before another word comes out of their mouth then they will have to perform what they had said they were going to do. If they do not do it then they get a slap by the person who called manchester. If some asks "are you going to kill yourself" and the person replies "yes" or "yea" and you call manchester then the person who replied yes must still perform it whether they said it or not.
