The phrase “sister from another mister” is a colloquial expression used to describe a close friendship or bond between two women who are not biologically related but share a deep connection, much like sisters. The term plays on the idea that while they may have different fathers (or “misters”), they have a sisterly relationship due to their shared experiences, values, or emotional support for one another.
This expression emphasizes the strength and importance of friendships that can feel as significant as familial relationships. It is often used in a lighthearted or affectionate context, celebrating the idea that family can be chosen and that strong bonds can exist outside of blood relations. The phrase can also be adapted for use with men, as “brother from another mother,” to convey similar sentiments in male friendships.
