Caygender is a gender where one's gender is typically too hard to distinguish, but at times can have sudden feelings of gender, like dysphoria. For instance, one might feel like their gender is too hard to figure out one day, then experience dysphoria/a brief feeling of gender for another day before returning back to their normal state. The world "cay" can be used as a prefix, such as cayboy, caygirl, caynon-binary, etc.
