Your third year of high school. Junior year means you are finally an upperclassman, after two years of crap at the sophomore and freshman ranks. However, as a junior, you still aren't the top dogs in the school, and still have another year to take orders from older douchebags. Junior year marks the beginning of the second half of your high school career...Good Luck.
Junior year is like playing the role of Robin for a whole school year.

A sexually deviant manuever in which a man becomes pregnant in the following manner: A man is performing oral sex on a woman while she is ovulating. The man punches the woman as hard as he can in her abdomen, dislodging the egg. The man then slurps as hard as he can, swallowing her egg. Next, the woman performs oral sex on the man until he ejaculates into her mouth. The woman and man snowball until all of the semen has been swapped into the man's mouth. The man then swallows his own semen. In his stomach, the man's sperm fertilizes the woman's egg and an embryo is formed. Nine months later, the man poops out his own child.
Arnold Schwarzenegger got freaky with Maria Shriver one night back in late 1993 and decided to perform The Junior on her; the movie, released later that year, was based loosely on that event.

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.

An 11th grade student in high school who generally sticks by the seniors instead of looking up to them, and of course, looks down upon the immature dramatic freshman/sophomores.
Joey is a junior who doesn't have to stress over graduation, nor does he have to be surrounded by annoying freshman/sophomores. Woo hoo.
