Oh they aren’t a pisstake, sadly. Youth social media sites like tumblr are full of this; they make them up by the minutes (“new gender just dropped!” is an actual Thing). You then get to make up a flag and pronouns and everything. 🙄
It just shows up the gender identity stuff fit the idiocy it is, since obviously none of these daft “xenogenders” has anything to do with “gender” in any meaningful way. You have to “respect” them, though, with a fully straight face (as it were), or else you’re a bigot spewing “terf rhetoric”.
Someone will be on the thread pretty soon to complain that we are all nasty mean bigots making fun of vulnerable trans people, and the thread will then be deleted as not “in the spirit of civil debate” like every other thread recently on xenogenders / catgender / spacecatgender / Neptunians / polyaroaces / otherkin / whatever.
