The phrase "to chop up" means to cut something into small pieces or fragments. It can be used both literally and figuratively, depending on the context in which it is used. For example, if someone says they are going to chop up some vegetables for a salad, then that person will actually physically cut those vegetables into smaller pieces using a knife. On the other hand, if someone says "I had to choke up my emotions," this means they had to hold back their tears or control their emotions in order not to cry.
