ok, so showing off and trying to use them in scrabble doesnt always secure as many points as a one syllable possessive noun, but there is something about impractical GRE words that replicate a viagra-like sensation of "i am incredible, hear me enunciate".
use in a sentence:
axl rose would not be considered a pulchritudinous specimen (although he is "hot" in a 'trailer park, still has all his teeth' way). however his hair is so refulgent that he would be a good spokesman for the 'long, loud and oh so happy shower' hair care products.
unfortunately there isnt a 5 syllable synonym for full of shit at thesaurus.com, but you may find a chronic blogger listed at dictionary.com
