Plural of bombast; plural instances of exaggerated, pompous speech or writing, or the padding material itself.
From 'bombast', which originally meant cotton or silk padding for clothing, then metaphorically extended to mean inflated, padded speech.
Bombasts work on two levels in Renaissance writing—they meant actual cotton padding in clothes AND the stuffed, padded language that people used to sound important!
