What does 'toast' mean in this movie?
In the movie, 2012, Charlie was radiobroadcasting at the top of the hill as a nearby volcano was about to erupt.
Jackson gets to him in order to ask for a map.
When Charile recognized Jackson, he said, "Jackson. What are you doing here? I thought you were toast.".
How does it sound? Is there an expression like that? Did he imply that he thought the man named Jackson already did die?
