The origin of the old sister-in-law: The word "old sister-in-law" comes from Tik Tok's comment area, which mostly comments on funny anchors and contains a kind of ridicule and irony.
Sometimes when I see a man with a more feminine behavior in the video, I will call him an old sister-in-law in the comment area. In fact, it is not an insulting word, but a teasing meaning.
The meaning of the old sister-in-law terrier:
The first meaning of an old sister-in-law is the daughter-in-law of the youngest brother, generally referring to the daughter-in-law of a cousin or the youngest distant brother. Sometimes an old sister-in-law is also a polite address for a woman who has no relatives or friends.
Later, it became popular in Tik Tok. When netizens see a male blogger behave more like a woman, they will call him an old sister-in-law in the comment area, which is actually a ridiculous statement.
