On a new word I just invented by accident

In the last two days, I misspelled the word "aristocrat" or its derivatives several times as "artistocrat". The last time I so misspelled the word, I had the idea that I should coin the word. "Artistocrat" would mean upper-class and wannabes in the art world, either aristocratic or pretentious artists or artistic or artistically pretentious aristocrats. Actually you could throw in artistic prima donnas, their sycophants and the rest of the demi-monde as well. Please use the word.
