Magniloquence

The word of the day is magniloquence. It is used to describe a pompous grandiosity in language, either spoken or written.

For example, instead of stating "This beer is pretty good," a person states instead, "The mellifluous tones of the oak tannins are barely hinted at, which gives a subtle yet pleasing buttery feel to the overall crispy richness of the beverage, even if the aftertaste is still a tad too structured."

As if they were a wine sommelier or some such character.

Magniloquence is in itself, an extremely magniloquent word.
