rave

( vi.)

   [WPI]

   1. To persist in discussing a specific subject.

   2.  To  speak authoritatively on a subject about which one knows very
   little.

   3.  To  complain  to a person who is not in a position to correct the
   difficulty.

   4. To purposely annoy another person verbally.

   5. To evangelize. See {flame}.

   6.  Also  used  to  describe a less negative form of blather, such as
   friendly  bullshitting.  `Rave' differs slightly from {flame} in that
   rave  implies  that  it  is  the  persistence or obliviousness of the
   person speaking that is annoying, while {flame} implies somewhat more
   strongly that the tone or content is offensive as well.
