humma: // excl. A filler word used on various `chat' and `talk'
programs when you had nothing to say but felt that it was important
to say something. The word apparently originated (at least with
this definition) on the MECC Timeshare System (MTS, a now-defunct
educational time-sharing system running in Minnesota during the
1970s and the early 1980s) but was later sighted on early Unix
systems. Compare the U.K's wibble.
