A sudden disease that sweeps eighth grade students all over the world. Similar to junioritis and senioritis. Eighth graditis symptoms include lack of motivation, excessive failure and laziness.
middle school kid: man, I just took the GEPA, I'm done with school I have eighth graditis.

older brother: Haha shut up I just took the hspa you suck! Just drop out (proceeds to beat up little brother until he cries).

middle school kid: nobody understands me..
