College Grade Intelligence

A psuedo-intellectual person who thinks their degree gives them a higher level of ability or social status.

They will often look down on people without a degree (or those who don't declare their degree) even though their distinct lack of experience leads then to make more mistakes than any person they consider below them.

See "man child" or "bad boss"

That project failed, huh?

Yeah, Jill's college grade intelligence messed everything up again.
