A crippling disease that strikes high school seniors. Most cases of senioritis tend to start after college applications and mid-year reports have been sent in. This entails a student not doing any work whatsoever, dismissive attitude, increased absences, general laziness, an over-excessive wearing of sweatpants/sweatshirts & resentment towards taking all those hard classes to impress a favorite college which the student most likely won't attend because of how expensive it is. The only known cure to senioritis is a phenomenon known as GRADUATION.
