Genderfade
Genderfade, also known as gendermelt, is a gender identity in which one's gender is only present when they think about it, and it fades or melts away when they aren't thinking about it. For example, genderfade individuals could go their entire day without a gender, only for it to reappear when someone asks them about it.
Genderfade is a non-exclusive version of nebulafade, which is exclusive to people/beings with ADHD; however, those with ADHD may choose to identify as genderfade and nebulafade, or just genderfade if their ADHD does not impact their gender in this way.
