An article by Rodney Clapp creates some new definitions. Here's my favorite:
Fliturgy: A hyperactive worship service designed for short attention spans--with a sermon under ten minutes, no more than two verses of any song sung, and prayer time limited to two minutes.
Here's another good one:
Egocessory prayer: A public prayer centered more on the pray-er and his or her eloquence and cleverness than on God.
This one's okay:
Lexlexia: When the pastor mistakenly preaches on a lectionary text not assigned for the day.
Another one:
Bulletinnitus: The dazed, ear-ringing sensation you get when the announcmements for the day drone on and on.
