They may also be battling bloviation: pretentious use of overly flowery language designed to impress the reader with the utter brilliance of the author. Elegance is a wonderful thing, assuredly. Opulence and bloviation, on the other hand, can go way too far...

It's fun to make fun of it now and then by doing it deliberately and ostentatiously, though. ;-) Just talk as if you have a potatoe lodged in one cheek, are speaking through a wod of cotton wool, and holding your tea cup with one pinkie sticking delicately out to the side, whilst gazing superciliously down your elevated Roman nose at the pathetic examples of humanity for whom you have deigned to drop a few petals of your divine wisdom. And pity them.

Ah! The ennui of it all! Pearls before swine, really.
