This one is a bit similar to 'pack in' but not exactly the same. 1. to put things into a bag or box in order to then take or send them somewhere. E.g. "The workmen packed up their equipment and went home". 2. When equipment stops working. E.g. "Our dishwasher has packed up again. We're going to need to ask someone to come and fix it." 3. To stop doing something, to quit. E.g. "I think I'm going to pack up my job and go travelling."
