Bush on August 14th uses the word
fabulous again:
With the base's Hangar 4 in front on him and two bleachers crowded with uniformed Marines and Navy personnel behind him, Bush declared, "I am proud to be commander in chief of such a fabulous group of men and women who wear our uniform."
Now, checking m-w.com's handy thesaurus, contrasted words for fabulous are believable, colorable, credible. Interesting that his political advisors allow this verbal tick to continue.
