I think the word elitist defines a person who prefers to interact with and inhabit a world of high cultural ideas, such as art appreciation and intellectualism - which is often associated with wealth and (in the old days) aristocracy. I think this is the context Charlatan is referring to.
Most often around here I think it is defined by the person who uses it. Often by someone who feels they are personally diminished simply by the opinion, desire or perspective of another person.
