"Toy boy" has come along in the last 10 or 15 years. It's British slang, from the 1980s. It refers to an attractive young man being kept as a lover by another person, by an older person, that’s the crucial thing: the older person is keeping the younger man as that person’s "toy boy".Toy boy（小白脸）这个说法大概是过去10到15年间开始流行起来的，是20世纪80年代的一个英国俚语。Toy boy指长相俊俏、被年纪大的人包养作为情人的年轻男子。这里传达的关键的一点信息是：年纪大的这个人把被包养的这个年轻男子当作自己的“玩物”。For example:He is a toy boy because he has been kept as a lover by a rich old woman for five years.他是个吃软饭的“小白脸”，因为他已经被一个富婆包养了五年了。
