Buzzword

“Buzzword (noun): A vogue term with a catchy or seemingly impressive cachet, especially one form the jargon of technology, business, or government.

‘The phrase is everywhere…it is, in part, modish nonsense following a direct linguistic line from such buzzwords as ‘buzzword,’ ‘synergy,’ and ‘stonewall.’” Sam Vaughn, The New York Times
