Chicken Liver means to be a coward.
This is not to be confused with being scared or frightened. A person can be frightened to do something but still do it, in which case he isn't chicken. Imagine two people on a diving board both are scared but one dives anyway. The other refuses to dive and could be called "chicken livered" or just "chicken"
