In Pulp Fiction (1994), Pumpkin says to Honey Bunny about difficulties in robbing liquor stores which owned by foreigners:
Pumpkin: We keep on, one of these g**k fuckers gonna make us kill him.
Honey Bunny: I'm not gonna kill anybody.
Pumpkin: I don't want to either. But they'll probably put us in a situation where it's us or them.
What does "us or them" mean?
I know the meaning of "us and them" (or) "them and us".
