Translations for 척하면 척이다?

Question

An intimate friend and native Korean speaker explained that I should have added a word in what I said to her, but she summarized with > 척하면 척이다 I think I get what she meant, but I began wondering what different ways we express this in english. As an example, I'm guessing this might be one way to translate it: > I'm picking up what you're putting down. but since the phrase itself may be subject to its own meaning, nuance may best be represented with a list of suitable translations.

Answer 1

I would say 척하면 척 is like 'I catch your drift' or 'we are on the same wavelength', and it basically means that the two people who are interacting understand each other even without saying anything explicitly but just with a glance :)
