Origin: American slang from the late 1800s, with clear examples in print by the 1880s and 1890s, including in Stephen Crane's 1896 novel The Third Violet. No documented practice or real event connects the phrase to any actual hat-related behavior, and that absence appears to be the entire point: a hat sits well above a person's mouth, nowhere near where actual speech comes from, making "talking through" one deliberately, almost comically nonsensical as a literal image. The phrase describes speaking with false confidence about something the speaker doesn't actually understand, and its own manufactured absurdity mirrors exactly the kind of confidently delivered nonsense it's used to call out.
