To bite the bullet means to face a hardship straight on, to bear something either physically or psychologically painful with bravery. Related phrase are bites the bullet, bit the bullet, biting the bullet. Biting the bullet is a cliché of the American Old West, cowboys are often depicted as biting the bullet when undergoing medical procedures without anesthetic. Bullets are made of lead, a soft metal, and biting a bullet was a distraction designed to stop a patient from crying out. The term bite the bullet is older than the 1800s, however, and may actually refer to how early guns worked. Gunpowder and a ball were previously loaded into paper cartridges. In the heat of battle, the soldier would rip open the tip of the paper cartridge with his teeth and pour the gunpowder and ball into his gun. Biting these cartridges and calmly loading a gun in the face of the enemy certainly meant facing a difficult situation with bravery, as in the idiom bite the bullet.
