"Little John" used as term of endearment for person with qualities related to that of being "little". Definition is fluid, but assigning the title "little" typically relates to a person who expresses kindness, compassion, empathy, and a certain level of optimism and joy toward life and other people. It also functions as an ironic name in this case, due to John being physically enormous, however that is not the original reasoning behind the naming of Robin Hood's "Little John."
