When a boy greets a girl, he calls her a fairy instead of her name. What does he mean?

It is popular to call others beautiful now, and he calls others fairies. If he often addresses people with beautiful women, then this fairy is higher than these beautiful women in his heart. Then if he often calls people fairies, then he is fluent. However, for this kind of boy who often calls girls by these names, I think it is inevitable to be a bit superficial. If he's basically not so attractive, then he should have a crush on this girl he calls a fairy.
