expertvillage 

A channel on YouTube that consists of people that call themselves "experts" with about 140,000 instructional videos. Expertvillage has a variety of different how-to vids. Most of these are useless, and the ones that are actually worth looking at are usually poorly done.

experticity 

A word used by non-experts to make themselves sound like an expert. Has more syllables than the word expertise, thus the speaker attempts to sound more intelligent, but usually fails.

Eddie: "I don't get paid enough to have to hear this, go down the hall and share it with Ray."

Expertitis. 

An affliction that causes considerable problems for people who become so expert at their chosen line of study or research that no one can understand those who have expertitis.

I've become so expert at dealing with highly specialized cases of wrongfully arrested cases that I have difficulty teaching my craft to others. That's Expertitis.

That's problematic because the truth is that a law degree is of no use to any would be expert who wants to specialize in the sort of cases that I deal with.

I have a 100% success rate, but "Expertitis" makes it difficult for me to understand why amateurs can't do what I do.
