At William and Mary, this is the last day of classes each semester. Everyone suspiciously carries water bottles around all day and gets raging drunk and goes to classes. Teachers know everyone is drunk and usually lets class out early.
Spring blowout > Fall blowout
Spring blowout > Fall blowout
ex: "Dude I'm so siked the last real day of classes was today. Tomorrow is blowout so we won't learn anything anyway!"
