how it makes me feel:

it's a pretty word. it lends itself to other pretty words. even one of its' definitions is pretty: "characterized by a series of graceful curving motions" that just sounds elegant. it sounds like a pinkies-up cocktail party where everyone is wearing tuxedos and talking about ostentatious things, like candelabras and fine china and stock portfolios. however much like an event so described, the word is boring. it's a word that could talk for hours and never actually say anything. it's window dressing - literary furbelow. i wouldn't say it sucks, at least not as a word, but it's a rather mediocre WOTD.
