vapoured (‘hee bid him putt vppe his rapier; but hee woulde not but vapored with it’):
To vapour was literally ‘to be emitted or diffused, in the form of vapour’ [see OED sv vapour v.]; thus metaphorically, ‘To use language as light or unsubstantial as vapour; to talk fantastically, grandiloquently, or boastingly; to brag or bluster’, and thus ‘To act in a fantastic or ostentatious manner; to show off; to swagger; to walk in with a swaggering air’, usually with the intention of impressing or putting down one's opponent. See OED sv vapour, v. 6. Often of soldiers swaggering (and presumably flourishing their swords, as here).
