Cách sử dụng
The word 'backfire' is used when something you do or say has the opposite effect than what you intended, and ends up causing problems for you instead. For example, if you try to make a joke and it offends someone instead of making them laugh, that joke has backfired. Or, if you try to make a situation better by interfering, but instead make it worse, you can say your actions backfired.
