Noun: A plan saved for the worst case scenario, or a backup plan.

According to Sarge from the popular web series Red Vs. Blue, what a shotgun to the face could be considered.
Griff: "And if the plan doesn't work?"
Sarge: "I've got a contingency plan."
Griff: "A shotgun to the face is not a contingency plan. I keep telling you that."
Sarge: "Of course it is! Just look how well it works for insubordination!"
