Lostagender is a neurogender or xenogender specific for systems that have lost adults. It is a gender that can only be described by lost adults, since the experience of being a lost adult in a system is so unique the gender experiences that come with it would be just as unique as the lost adults themselves.
It can be used as a modifier or alongside other genders to help describe an age forger's experience with gender, such as losteagirl, lostaboy, lostaenby, etc.
