What is an address book?

As a network language, address book is used to express "homosexuality". Because the pinyin abbreviation of the address book is txl, and txl ranks high in the pinyin input method as homosexuality. The man's address book means he looks like a homosexual, and the woman's address book is Les. If you just talk about the address book, you can only know the sexual orientation of the other person, but you can't tell whether it is 0 or 1.
