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.

When your in your very last years in college, where your emotionally drained, you have no care in the world, anything and everything irritates you, you often skip class, lazy and tired aren't even the worst of it. A student will find himself/herself lazy and very sleepy. Your emotionally, physically and mentally drained. You tend to skip doing homework and try and stall by doing something else.
A college student who has senioritis would find themselves sleeping in their cars more when they should be at work and or in class.
