Is buzzword a buzzword?

I have the impression that a "buzzword" is a relatively new coinage, popular with a somewhar small group. Since "buzzword" been in use for several years and is widely known, it is not longer a buzzword.

buzz.word (buz´wûrd) n. A usually important-sounding word or phrase used primarily to impress laypersons.

buzz.whack.er (buz´wak er) n. A person who receives some degree of pleasure in bursting the bubbles of the pompous.

The buzzword of all buzzwords, of course is:

onomatopoeia

Please do not ask me to explain my thinking. You either get it or you don't.
