Buzz is a busy little word. Buzz meaning a busy rumour dates from the early 1600s but made a revival in America in the 1950s when it took on the meaning of the latest news. In the late 19th /early 20th century, buzz also meant to call someone on the telephone and buzz off originally meant to ring off, whereas from around the 1920s it began to mean go away. During the 1930s, buzz took on the meaning of a pleasant sense of intoxication. During WWII, for aviators, buzz meant to fly very low. Finally, we have buzzword meaning fashionable jargon, which dates from the mid-1960s.
