This question already has an answer here:
What is a word in the English language to describe someone who purposely and excessively uses too many complex words, usually looking them up in a thesaurus, to seem more intelligent in their writings?
I found the term "waxing prolix". But, this doesn't seem to cover the fact that the person is doing this purposely to seem more intelligent than they actually are.
An example. "The feature is a pastiche of mediocrity and boorish cynicism. They are a political and artistic hack pandering to an assemblage of bitter philistines." The person could have just as easily said, "I'm not a fan of this movie or it's actors".
They simply sound like they are trying to sound more intelligent by using an arsenal of words that are not often used in the common tongue. Perhaps elevating themselves above their own audience?
Not a duplicate of this because the accepted answer to that question does not describe the word I am looking for.
