Gendertumble, also called tumbleweedgender or tumblegender, is a xenogender which is cluttered, complicated, and is constantly moving around. It may also feel like it's in the center of a large, empty, desert-like space. Or, similarly, it may be an empty space itself, making the gender paradoxical in nature.
This gender can be used as a gender on its own, used alongside another gender, or used as a gender modifier. In the case of being a gender modifier, one may combine it with another gender term (example: tumbleboy, tumblegirl, or tumblenonbinary).
