Wikipedia
A buzzword (also fashion word and vogue word) is a term of art or technical jargon that has begun to see use in the wider society outside of its originally narrow technical context by nonspecialists who use the term vaguely or imprecisely. Labelling a term a "buzzword" pejoratively implies that it is now used pretentiously and inappropriately by individuals with little understanding of its actual meaning who are most interested in impressing others by making their discourse sound more esoteric, obscure, and technical than it otherwise would be. Buzzwords differ from jargon in that jargon is esoteric but precisely defined terminology used for ease of communication between specialists in a given field, whereas a buzzword (which often develops from the appropriation of technical jargon) is often used imprecisely among non-specialists.
