Senioritis might not be considered a bona fide disease, but it can be hazardous to your academic health.
You’re familiar with the term, right? It’s so prevalent, it’s even in the Urban Dictionary:
Senioritis: noun. A crippling disease that strikes high school seniors. Symptoms include laziness, an over-excessive wearing of track pants, old athletic shirts, sweatpants and sweatshirts. Also features a lack of studying, repeated absences and a generally dismissive attitude. The only known cure is a phenomenon known as “graduation.”
