What does little brother mean?

In Qingdao dialect of Shandong Peninsula, "little brother" means young people, and generally appears in provocations and jokes. In some cases, it also refers to unhealthy young people who are idle in society. Similarly, in Qingdao, women are called "Xiao _". Qingdao's "little brother" is aimed at social idle youth and unhealthy teenagers.

The word "little brother" didn't mean it at first, but because the word "man" in public address corresponds to a lady and the word "gentleman" corresponds to a lady. At first, the word "little brother" corresponds to a little brother, and of course a little sister should have a little brother. This is a neutral title.
