Talk a blue streak
Meaning
To speak very rapidly and continuously for a long period, often with great enthusiasm or excitement.
Origin
The vivid image of a 'blue streak' first emerged in the 19th century to describe anything moving with astonishing speed and intensity, often likened to a flash of lightning or the almost invisible blur of a whip cracking through the air. This powerful visual metaphor for unstoppable momentum quickly extended beyond mere physical speed. When someone began to 'talk a blue streak,' they were speaking with such relentless rapidity and continuous flow that their words seemed to blur together, an unbroken torrent of sound. The phrase perfectly captures the sensation of an overwhelmingly fast and non-stop conversational delivery, as if the speaker themselves had become an unstoppable force of nature, much like a bolt from the blue.
Examples
