The Megillah, which translates to scroll, is read twice on Purim, once at night as Jewish days begin the night before and once during the morning to remember that the Jews cried out for help during the day and at night. It tells the story of Purim and during this, every time the name Haman is read, it is met with booing, stomping, and using groggers (noisemakers). His name is so evil, it should be drowned out but must be said during the reading.
