Speakers of the English language, mindful of the lightness and unsubstantiality of floating air and gas, have put several airy words to good use over the years to describe the act of talking idly or boastfully. The earliest such word is "blow" (as in "he kept blowing about his new job"), which drifted into English sometime about 1400. "Vapor" wafted into the language in the 1620s, and a little over 200 years later "windbags," later also known as "gasbags," not only blew and vapored but also "gassed" about anything they could.
