where did the term break a leg originate
Break a leg Urbane Irish nationalist Robert Wilson Lynd published an article, "A Defence of Superstition", in the 1 October 1921 edition of the New Statesman, a British liberal political and cultural magazine. Lynd regarded the theatre as the second-most superstitious institution in England, after horse racing. In horse racing, Lynd asserted, to wish a man luck is considered unlucky, so "You should say something insulting such as, 'May you break your leg!'"[6] Lynd did not attribute the phrase in any way to theatre people, though he was familiar with many of them and frequently mingled with actors backstage.
Roughing the kicker In 1914, the term "roughing the kicker" came into use. Previously, it was known as "running into the fullback after the kick."[4]
