Senioritis: A term used colloquially in the United States and Canada to describe the decreased motivation toward studies displayed by students who are nearing the end of their high school or college careers. It is typically said to include slowness, procrastination, apathy regarding school work, and a tendency toward truancy.

Many high school and college students find themselves in a type of lame duck situation: their plans are made and a new chapter in their life is about to begin, so finishing the current chapter (the current term separating them from graduation) becomes just a formality or "holding pattern."
