Genderice (pronounced gender-ice) is a microlabel of genderfluid that describes a gender where one's genders feel blocky and cold, separated within the genderfluid, like ice. One's gender is still genderfluid, and it changes, but the genders that one switches through feel hard and separated from each other. They feel static, but not that they don't change. The genders might change slower than usual in some people, might feel cold or hurt a little bit to be them, or might feel hard to access. Technically, not all genders experienced in genderice have to be genderice genders, but usually they all are.
Genderice is also a term for xenogenders that feel cold, and blocky, like ice, or genders that relate to ice. A similar term is Glaciagender or Hielon, but is still noticeably different.
