A day chosen by a high school senior class for the entire class to skip school. Typically falling on the Monday after prom, it tends to infuriate teachers and school administrators alike. The day has become less popular in recent years as the bureaucracy of public schools in the United States is becoming increasingly communist. For those who participate, the day continues to symbolize rebellion against overcomformity and the American desire for individuality.
