Today’s idiom is “to miss the boat”. It is used to talk about a time when someone has missed a good opportunity. For example:
My friend said I should invest in that stock, but I didn’t. Then, it went up to ten times its original value. I really missed the boat on that one.
You should apply for this job. It’s a great opportunity! You don’t want to miss the boat, do you?
My brother could have made a lot of money if he had invested in that company right away. Unfortunately, he waited too long and missed the boat.
As you can see, this idiom is usually used in business situations, especially about investing in something and having the opportunity to make money.
