I've been reading the script of "the sunset limited",but there are some terms i don't quite understand.Guys,please help me with it !

thank you in advance!

here's the quotation:

white:That world is largely gone now.Soon it will be wholly gone

black:You're saying that all this culture stuff is the only thing between
you and the Sunset Limited.

white: It's a lot.
black: But it busted out on you.

.....
black:You break bread with a man,you've moved on to another level of friendship.I heard that's true the world over.

white:Probably

black:Probably?

white:I like probably.

black:Probably from you is worth a couple of damn rights anywhere else.
