Derafluid is a gender under the umbrella of klimigender and klimifluid. It is when one is deragender, meaning ones gender can be described as being a specific temperature, to the point that one could say what degree it is, however that exact temperature changes. For example, ones gender could fluctuate between -24°F to 73°F, or 5°C to 68°C, etc. but as one's gender fluctuates one always knows exactly what temperature it's at.
Derafluid was coined by the Tumblr blog mogaiheaven on November 9, 2018.
