BOSTON (Reuters) - A New Hampshire man has been charged with assaulting his girlfriend after flying into a violent rage when she beat him in an arm-wrestling match and called him a "wimp."

The Union-Leader newspaper reported on Wednesday that Raymond White and Lisa Smith had been drinking early on Tuesday when she remarked that he didn't have any muscles and challenged him to an arm-wrestling match.

Smith mocked White after winning the contest, and he responded by grabbing her by the hair, dragging her down a set of stairs and punching her several times in the head, the paper said, citing court documents.

White was charged with simple assault, a misdemeanor. He pleaded innocent in Manchester District Court, and a trial was set for September.
