title: Pop up message box in PyGame
body: <p>I want to create a pop up window inside the game which will display result for a small game, if you click OK, the game continues, but that doesn't matter. How do you even create such box so it will pop up when I call it? I read question with <code>pgu</code>, what is <code>pgu</code>? Is it another external library?</p>
