What does your mother mean?

Answer 1

It is usually a phrase to belittle someone, in the way of making fun of someone in your family. It mostly has no meaning whatsoever, and is used as an insult when someone is defensive about something.

Answer 2

It means, "Do what your mother tells you to do" or "Obey your mother." Here, "to mind" = "to obey"

Answer 3

Minding means doing what someone says.
