shotgun
n//ˈʃɑtɡʌn//hagelgevär, framsäte
(firearms) A gun which fires loads typically consisting of small metal balls, called shot, from a cartridge.
(slang) The front passenger seat in a vehicle, next to the driver; so called because the position of the shotgun-armed guard on a horse-drawn stage-coach, wagon train, or gold transport was next to the driver on a forward-mounted bench seat. Can also be used in situations of claiming other resources such as bedrooms.
