"Sack it off" is a slang expression commonly used in informal conversations among friends or acquaintances in British English. It means to give up, stop doing or cancel something. It suggests that the person is frustrated or no longer interested in doing the thing, and wants to quit. For example, if you and your friends were planning to go to a party but suddenly you changed your mind, you could say, "I'm going to sack it off, I'm not really in the mood to go out tonight."
