REFERENCE

talk through one's hat

idiom
Meaning

To speak lacking expertise, authority, or knowledge; to invent or fabricate facts.


Origin

disputed origin

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.

Examples
SIMPLE

He's talking through his hat again about politics.

CONTEXTUAL

The guest on the show was talking through his hat, claiming facts that anyone could easily disprove.

COMPLEX

Though he spoke with confidence, the critic was clearly talking through his hat, having never set foot in the country he described so vividly.
