Break a leg!

Definition

Theater

  • Traditional wish of good luck among performers in the theater,since a wish of 'good luck' is considered a jinx (see taboosand superstitions). There may be a connection to the oldtheatrical belief that it is a good omen to stumble or fall over whenmaking one's first entrance. Another suggestion is that the phrasealludes to the fate of the actor turned assassin John Wilkes booth(see Booth family), who broke his leg when he leaptfrom the box occupied by his victim, President Lincoln, onto the stageof Ford's Theatre.
