One insult I’ve seen spreading lately is “over educated”, usually in reference to someone saying a more mainstream viewpoint in the face of a less well known/contrarian/esoteric/based viewpoint 

Ie

“That over educated bitch of a doctor thinks seed oils don’t hurt you”

The Farcaster formerly known as Kchamp. Books, beats, bodybuilding, bright ideas and beautiful things.

that is not the dunk they think it is. 

I’d take called being over educated as a compliment
