Refers to the process of researching and writing a dissertation. Used in place of similar descriptors, such as writing or studying, in order to emphasize the great scope and magnitude of the work taking place. Often used by graduate students to describe their work schedule.

Other teacher/professor: yeah! omg that would be amazing let's call it a DISSERTATION...that'll get 'em
