clevarity
a unit explaining exactly how clever a person, or a person's statement is.
The person that made up this word must have had a lot of clevarity, or maybe they were just really cocky and thought they were clever so they posted it on urban dictionary just to be able to use it in a sentence... Then if any one doubted the clevarity of using the word the creator could tell them to look it up, and the word would be on urban dictionary... with a rather odd example.
