Slackmester 

A period of time during a school year when academic responsibilities are pushed aside in favor of non-academic pursuits. In slacker terms, an entire semester of going to the bar every night instead of studying. See also, alcoholism.

While it may happen at any point in a college, graduate, or high school career, typically a slackmester occurs in the last semester of a given school period, when students suddenly realize how pointless hard work really is.
