EOS

Short for Early Onset Senioritis. It typically occurs during the final few weeks of a high school junior's life, however it is not unusual to see some cases that begin after the second semester has begun.

Symptoms include fatigue, lack of motivation and at times narcissism.

See senioritis.

Junior 1: It's so sad that all our senior friends are graduating
Junior 2: Isn't it?
Junior 1: Did you study for Smith's test?
Junior 2: Nah, I'm suffering from EOS
