A person who acts like they’re super smart, but they’re just faking it. Usually has a PhD, but it doesn’t mean much.

"She said she’s a hackademic. I asked her what that means. She said ‘you wouldn’t get it.’", @ConfusedPerson
"He’s got a PhD, but he still uses Google for everything. Hackademic trash.", @BasicHuman
