ur mother a brother

A phrase not to be used too often. Once this is said, the world enters a vicious downfall. The most devestating thing anyone could say.

Dan: ur mother a brother

mother from another brother

A sister that treats a brother like their own child.

The sister trying to manhandle him pretty much shows she's a mother from another brother
