Bombastic, flowery, pretentious, verbose all describe a use or a user of language more elaborate than is justified by or appropriate to the content being expressed. Bombastic suggests language with a theatricality or staginess of style far too powerful or declamatory for the meaning or sentiment being expressed: a bombastic sermon on the evils of cardplaying. Flowery describes language filled with extravagant images and ornate expressions: a flowery eulogy. Pretentious refers specifically to language that is purposely inflated in an effort to impress: a pretentious essay designed to demonstrate one's sophistication. Verbose characterizes utterances or speakers that use more words than necessary to express an idea: a verbose speech, speaker.
