A phase diagram for water. In the solid phase there is a label “man(?)”. The triple point is labeled “femboy triple point”. The liquid phase is labeled “boy”. The gas phase is labeled “girl”. The supercritical point is labeled “‘just hot’ critical point”. The supercritical phase is labeled “supercritical gender fluid”.
