Vacansgender is described as currently being empty or vacant, but having the capacity to be gendered or occupied.
There are ways it can become occupied, including but not limited to being perceived as a certain gender (custodiogender), thinking about a gender (thoughtgender), or purposefully gendering it (cinngender). The occupied feeling may or may not be temporary. One may or may not continue to identify as vacansgender if one's gender is occupied.
In some cases it is able to be any gender, but it might also be available to only specific genders, in which case you can replace -gender with the appropriate label, e.g. vacansfin, vacansboy, vacansabinary, vacansfloren.
It's possible for one's gender to never get occupied. As long as one's gender is or was vacant/available at some point in time, then one can be vacansgender.
