Origin & History

Origins and dates here are approximate summaries. Many idioms have disputed or unknown origins, and not every date has been checked against a historical dictionary, so treat specific dates and stories as a starting point rather than a citation.

Whips lash quickly, so the metaphor applies to speed of mind.

Ad appeared in advertisements and sports talk by the late 1800s.
