Xenopronoun

"Themis touches upon the center to which discussions on who exactly lies behind the category tucute have moved on truscum subreddits – focusing less on the nonbinary figure, while constructing a, ususally young/teenage, person using neo- or xenopronouns (i.e. zir, xi) and deemed ‘inventing’ xenogenders, i.e. catgender (but also, as Themis remarks, agender for instance)."

"Pronouns: Words that replace a noun in a sentence such as “she/her”, “he/him”, or “they/them”. Alternatively, there are neopronouns like “xe/xem” or “ze/zir”. Xenopronouns are a subsection of neopronouns in which a different noun is used in place of a pronoun."

"Also consider the emergence of neopronouns and xenopronouns. The New York Times explains neopronouns reflect one’s identity as “a person, place or thing.” […] It gets even crazier with xenopronouns, which are described as “a type of hypothetical neopronouns that cannot be understood by humans and/or expressed through human language.” Of course, the fact that they cannot be understood by anyone else makes the individual claiming them extra special."
