Hello Anastasia, Hunny is a corruption of the word Honey. You referenced Winnie the Pooh, which is told from a child's point of view. Because of this, many of the words that appear in the books and movies are misspelled, including that sweet liquid. Some people think it's cute, so the practice of misspelling it has persisted in pop-culture. As you stated, "Honey" is a term of endearment, along with the lines of "Sweetie", because love is a sweet emotion. When some people write it, they write 'Hunny' to make it more cute or endearing, but the proper term is 'Honey'.
