Cách sử dụng
The expression "kick in" usually means something that starts or begins to happen. For example, if you take medicine and it takes 30 minutes for the effects of the medicine to start, you can say "The medicine will kick in in 30 minutes." Or if you have a car that won't start, but it finally starts after you keep trying, you can say "The engine finally kicked in." It's a casual expression and is often used in everyday conversations.
