Called after someone else calls Shotgun, the Cumbria Shotgun overrides the original shotgun because if the original shotgun caller doesn't move out of your seat, you actually go on a mad shotgun killing spree. Google "Cumbria Shootings".
*Derrick and his twin are about to get into a car*
David: SHOTGUN!
Derrick: CUMBRIA SHOTGUN!
David: Mate, I already called shotgun. I'm getting in the front!
Derrick: CUMBRIA. FUCKING. SHOTGUN. *Chk-CHK*
