burble
     
        [Lewis Carroll's "Jabberwocky"] Like {flame}, but connotes
        that the source is truly clueless and ineffectual (mere
        flamers can be competent).  A term of deep contempt.  "There's
        some guy on the phone burbling about how he got a DISK FULL
        error and it's all our comm software's fault."  This is
        mainstream slang in some parts of England.
