A more common example is the meme about women and men colors. Women have magenta and salmon, while men call both pink. This has not much to do with linguistics or eliminating ambiguity.

You say 'pink', you mean 'pink', and if the other person wants to know which pink, they ask?

edit: this was a strawmanning, colors are a non-issue. But there can be situations where there are 2 objects, you say a word to refer one of the objects, and your partner thinks about the other object, and neither of you think that it was ambiguous, so you don't clarify until it's too late. Like there is a dead bear and a bear cub, you say 'bring the bear' and you mean the cub, and they mean the dead bear.
