Etymology

The term "shotgun" emerged in the early 19th century, combining "shot" (small metal pellets used as ammunition) and "gun" (a tubular firearm). The logic is straightforward: a gun designed to fire "shot" rather than a single bullet. The colloquial sense of the car seat (early 20th century) derives from stagecoach guards who rode upfront with shotguns for protection. The verb and adjectival uses extend the idea of forceful or immediate action, metaphorically linked to the weapon's rapid discharge.

  3. The bandit was shotgunned by the sheriff during the standoff.
