seniorosis

Mistakenly called senioritis (which translates literally to "inflammation of the senior"), seniorosis is a diseased condition of the senior. It is a condition in which seniors in high school, college, or graduate education finally burn out and can no longer function as they normally do. Some symptoms include extreme laziness, hanging out with friends all the time, watching excessive amounts of Netflix and YouTube, skipping classes, failing to turn assignments in on time, ruining one's GPA, and just no longer giving a crap about anything.
