Phrase: Neither here nor there
When a comment, answer, or statement is not related to the topic of discussion and, therefore, not relevant, neither here nor there is used.
For example, you give your husband a choice for supper tonight: nabe or buri teri.
He says, “Curry!”
You reply, “Curry is neither here nor there; the options are nabe or buri teri!”
If he repeats “Curry!”, then push comes to shove and there is no supper for him, right?
