rave

[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.
