...its a game I've seen on Dick and Dom in da Bungalow. In case you haven't seen it you go to a public place, ie an art gallery, library etc, there has to be at least 2 of you. Then you take turns saying bogies, but everytime you say it you have to say it louder to see how loud you can go. The winner is the one who shouts it the loudest. Its so mature, try it!
