A reference to the consistent cycle of sickness after returning from the The Hague International Model United Nations conference in the The Hague, Netherlands. The Hague Plague takes many forms (it varies from year-to-year), but it mostly entails stuffy nose, coughing, trouble sleeping, throat soreness, and a general feeling of internal death. While used by many of the delegates after THIMUN, it is mostly used by the schools from the United States.
