Cách sử dụng
The expression "drop somebody in it" means to put someone else in a difficult or awkward situation. It is used to describe a situation where someone causes trouble or puts someone else in trouble by revealing information or doing something that was not supposed to be done. For example, if you accidentally tell your teacher a secret that your friend told you, you have "dropped your friend in it" because now your friend might get in trouble. It's usually used in a negative context and is not a nice thing to do to someone.
