Project-Induced Somniaphobia Disorder

Project-Induced Somniaphobia Disorder (sometimes referred to as Project-Induced Insomnia and abbreviated as PISD) is a term referring to the tendency of projects to cause students to trade sleep for valuable work time. PISD is often felt when students have a large sum of work due the next day or when the student is feeling overly productive. Some people have chronic-PISD (cPISD), where the person is compelled at nearly every moment of their free time to do something school related, such as completing homework early.

Origin
The joke came into existence on Thursday, October 12th, 2017 in IPolcathica's SMS group chat. It was named when Joe Askharoun had admitted to the group that he had been "overly productive" the entire week, but at the expense of sleep.

Etymology
Originally, the term was "Project-Induced Duermophobia," where duermo- comes from the Spanish "yo" form of dormir, which means "to sleep," and "-phobia" means "fear of," but was decidedly too complex and hard to explain. The current form comes from the Greek root -somnia-, which means "sleep." The alternative form comes from "insomnia."
