talk through one's hat

== English == === Etymology === Attested from the late 19th century in the United States in the sense of “bluff”; the sense “speak without authority or knowledge” developed later. Although some people speculate a connection to a former requirement that British Members of Parliament wear hats, the connection is implausible. === Pronunciation === === Verb === talk through one's hat (third-person singular simple present talks through one's hat, present participle talking through one's hat, simple past and past participle talked through one's hat) (idiomatic) To speak lacking expertise, authority, or knowledge; to invent or fabricate facts.
