Cách sử dụng
The expression "cop out" means to avoid taking responsibility or to not do something that you are supposed to do. It is often used when someone takes an easy way out of a difficult situation. For example, if someone promises to help you with a project but then decides not to do it because it's too hard, you could say they "copped out" on their promise. It is generally not a polite expression, so be careful how and when you use it.
