A disease that occurs when high school seniors have applied to and/or been accepted to college. Senioritis cripples any and all drive to do homework, and seniors replace homework time with activities like parties, pranks, and reading about senioritis on Urban Dictionary.
I got senioritis after finishing my application; why would I want to write an essay for English? Let's go play tag.
