Da fluid-retention-related condition of either having puffy eyes from studying too many books, or getting a "swelled head" from thinking dat you're some sort of elite superiorly-educated college-stiff.
An old "Bazooka Joe" cartoon gave a hilarious example of "Acedema":
College professor: Say, Sonny, can you tell me where Cedar Street is?
Mort: Yes, Sir --- turn right at the next corner, and it's two streets over.
Bazooka Joe: Why are you strutting, Mort?
Mort: I knew something that the PROFESSOR didn't!
