look up any word, like dirty sanchez:
 
1.
A myopolymath is a person who knows everything and yet understands nothing.

Or, more loosely, those who proclaim knowledge of just about everything, but whom have precious little understanding of anything.
I spoke with a myopolymath the other day who rattled off an incredible number of random facts, and when I asked him what they really meant, he just said that wasn't the point and continued his recitation.
