Bill Clinton is the only U.S. president with a hand gesture named after him: the “Clinton thumb.” This subtle gesture involves pressing the thumb against the index finger while making a fist, often with the hand slightly bouncing for emphasis. It became a signature part of his public speaking style—authoritative without being aggressive, confident without pointing. The Clinton thumb was praised by communication coaches and political strategists for softening strong rhetoric and conveying sincerity. Unlike the more jabbing gestures of past politicians, Clinton’s thumb allowed him to make forceful points without appearing confrontational.
