A
boring long-winded,
up on a soap box speech, usually about some
banal topic. If used in the
religious context, usually denotes some
abhoringly long sermon on a
self-serving topic.
If used in the
civillian world, it usually refers to a public
denouncement, with several
character attacks, and defaming
innuendos.
A good example would be any
press release from the
Moral Majority.
