Patter

Patter is a glib rapid speech, that accompanies and complements some actions, e.g., of an auctioneer, salesperson, caller (dancing), or comedian.

It was a slang word for the secret or cant language used by beggars, thieves, Roma people, etc., hence the fluent plausible talk that a cheap-jack employs to pass off his goods. Many illusionists, e.g., card magicians use patter both to enhance the show and to distract the attention of the spectators.

Antipattern

In software engineering, an antipattern is a design pattern that appears obvious but is ineffective or far from optimal in practice.
