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.
The AP student, having junioritis, defined junioritis on Urban Dictionary to procrastinate on homework.

A terminal strain of Senioritis that is obtained by excessive laziness and contact with infected seniors. Junioritis tends to attack young people around the age of 17 or at the end of there 3rd year of high school. This tragic disease affects a person’s ability to obtain any form of motivation used to achieve tasks specifically related to public high schools; it also affects a person’s ability to judge long spans of time, often giving the infected individual a false sense of hope and relaxation. In its later stages this disease can lead to failing of classes, summer school and in some extreme cases failure to graduate, coma, and death. Some medications for this illness include Ritalin, caffeine, and excessive strikes to the individuals face and groin.
