An infection of the brain exclusively found in high school students in their third year. Symptoms include but are not limited to laziness, procrastination, demotivation to do homework, and taking on rigorous course loads without wanting to do the resulting work. Most infected students manage to avoid temptation to fail classes. Believed to be caused by taking too many AP/college/honors classes. There is no known cure, but treatments include snow days, long weekends, electives, study halls, "study" groups (a.k.a. doing five minutes of homework before playing Halo), and chemistry teachers conducting dangerous experiments that go haywire.
Not to be confused with senioritis.
