英語版FF9日誌26 : We're all dead meat.

Cinna:
Zidane, I'm surprised you made it! I can't believe you jumped off! You're nuts, you know that?

Zidane:
I didn't jump off. I got thrown out from the impact. So, is everyone okay?

Cinna:
Yeah. We've all got the devil's luck. But if we don't find Princess Garnet, we're all dead meat.

I'm dead meatで「もう駄目だ、おしまいだぁ」という意味です。

ちなみに、You're dead meatだと、「お前はもうおしまいだ」という脅し文句になります。
