History of Phrases

Before it meant holding a grudge, this phrase described a literal invitation to violence. In 19th-century America, men looking to prove their toughness would balance a piece of wood on their clothing, daring rivals to knock it off. This precarious object acted as a tangible boundary; touching it signaled the immediate start of a brawl, cementing the link between carrying a burden and looking for trouble.
