The nickname for the event more formally known as freshman disorientation. The opposite of freshmen orientation, the purpose of this eventful is for upperclassmen get all of the freshmen really drunk and humiliate them.
Oh did you go to the dorm's dis-o last night? I heard they served pink panty droppers and then locked all of the freshmen in a closet.
