This is a term worse than "ur mom gay", "ur dad lesbian" , "ur granny tranny", or even "ur sister a mister"...

Greg: shit, well then that means "ur granny tranny"
Dave: "ur sister is a mister"

Dave: don't you dare say it i swe--
Greg: "ur brother a mother"
*entire quantum-verse crumples, releasing radioactive materials that prevent and form of human life from existing for the next century*
