Cách sử dụng
The expression "kiss something goodbye" means to accept that something will not happen or to give up on a hope or wish. It is used when we know something bad is going to happen or when we have lost all hope of achieving something. For example, if you forget your phone on the train platform and it's gone, you may say "I can kiss my phone goodbye, it's gone forever." It is a way of accepting a loss or failure.
