A term used in the game show Deal or No Deal when the majority of low amounts are still in play, but there are two high amounts to justify continuing the game.
Howie Mandel: Now the question is: deal or no deal.
Contestant: $275,000 is life-changing, but the $300,000 and $400,000 boxes are still in play! So I still have my 'safety net'. No deal!!!
