Fluid

Cassfluid

Indifference to gender with something in motion — the gender itself, how little it matters, or both.

  • No settled flag

A shorter entry: the essentials, written to the same standard. The fuller guides are on the main identities.

What it is

Cassfluid is two words welded together. Cassgender: you might have a gender, and it does not matter much to you. Genderfluid: something moves. Put together, the word covers three shapes, and the people who use it do not agree which one is the real definition.

The Cassgender Community Network blog on Tumblr, the nearest thing to a record we could reach, lays out all three: the indifference is fluid while the gender stays put; the gender is fluid while the indifference stays put; or both are moving. If you fit somewhere along those lines, the blog says, you could be cassfluid.

What it is not: cassflux, where the gender sits still and only how much you care rises and falls — that one has a wiki entry and a flag of its own. And it is not plain genderfluid, where the changes matter to you. Be honest with yourself about how thin the record is here. No community wiki we could fetch has a page for it; the definition lives in a Tumblr answer and an Urban Dictionary entry. It can still be the exact word for you. It just will not win any arguments.

Pronouns

Nothing about the word fixes your pronouns. If the gender moves, some people move the pronouns with it. If the caring is what moves, most settle on one low-effort set — correcting people is exactly the sort of gender admin a cass week cannot be bothered with.

Does this sound like you?

You noticed your gender had changed about a fortnight after it did, because it was not worth watching.
Someone asks what your pronouns are today and your honest answer is a shrug that is not a refusal.
You have used the same they/them for years, not as a statement, but because it was the least work across every version.
Some weeks you can feel a specific gender, quite clearly, and the feeling is: fine, whatever.
You have ticked three different gender boxes on three different forms this year and none of them felt like lying.
Every so often it matters — you want the word, the pronoun, the look — and then it stops mattering again before you have done anything about it.
You read the genderfluid page and thought: yes, but with less drama.

Nearby identities

The distinction is the useful part.

Cassflux

Gender still, caring moves. Cassflux has a wiki record and a flag; cassfluid is the messier cousin where the gender itself may also shift. If nothing about your gender swaps, cassflux is the tighter word.

Compare Cassfluid and Cassflux →
Cassgender

The steady version. Gender exists, or might, and is unimportant, year in year out. Cassfluid needs something to be moving.

Compare Cassfluid and Cassgender →
Genderfluid

The gender changes and the changes matter. If each shift comes with a real pull — clothes, pronouns, a different name — that is genderfluid, not cass.

Compare Cassfluid and Genderfluid →
Gender Apathetic

Not caring about gender or gender labels, steadily. Very close to cassgender; the difference from cassfluid is that nothing is in motion.

Compare Cassfluid and Gender Apathetic →
Agender

No gender there at all. Cass leaves a gender in the room — it just does not get much attention.

It might not be you if…

  • Your gender moves and you care about each move. That is genderfluid; the cass part is not there.
  • Nothing moves — gender or caring — and you would like a word for "I don't think about it". Cassgender says that with far less explaining.
  • What comes and goes is how safe it is to care, not how much you do. That is your surroundings moving, not you.
  • The flat weeks flatten everything else too — food, friends, music. Look at that first; a word will keep.

Questions people ask

What's the difference between cassfluid and cassflux?

Cassflux: the gender sits still, and how much it matters rises and falls. Cassfluid is broader and blurrier — the gender may move, the caring may move, or both. If you only need the caring dial, cassflux is the better-documented word.

Is cassfluid a real term?

It is a term real people use. It is also barely recorded: a Tumblr community blog answers a question about it, an Urban Dictionary entry defines it, and the community wikis we could reach have no page for it. A word's obscurity does not make your experience less real. It does mean you will be explaining it.

Does cassfluid have a flag?

Not one we can verify. The Cassgender Community Network said as much when asked. This site shows an honest hatched chip rather than inventing one.
