Middlegender is a neurogender or xenogender specific for systems that have middles/systeens. It is a gender that can only be described by middles/systeens, since the experience of being a systeen in a system is so unique the gender experiences that come with it would be just as unique as the middles themselves.
It can be used as a modifier or alongside other genders to help describe an age forger's experience with gender, such as middlegirl, middleboy, middlenby, etc.
