Seperedian is a neurogender and/or xenogender for median systems. It is a term used to describe a median system that, as a whole, shares a single gender except for one headmate who differs in gender from the rest. For example, if a median system has thirteen headmates in all, out of those headmates, twelve of them would be girls while one is agender.
Similar terms include mediangender, mediseperus, and fluidian.
