What is the Meaning of the Expression
SLIM TO NIL?
Slim means thin.
Nil means nothing, or zero.
This expression is often used to describe your chance at something (i.e., the possibility of you succeeding at something).
It’s a slightly humorous way of saying that you have almost no chance, or no chance at all.
1. John: Marie is gorgeous. Do you think she would go out with me?
Josh: I’d say your chances on that are slim to nil.
2. See STORY example: … the odds of me getting him to go back in the bike trailer are slim to nil.
This sentence means that the author had very little possibility (maybe no possibility) of getting Jesse back in the bike trailer.
