My pronouns are her/she and are to be used the opposite way around to she/her.
Cool; I'll have cad/bury for mine!
If this thing truly is meant to be international, it will presumably include all pronouns in all languages - whether standard in those languages or made up - including languages that English speakers often find almost impossible to pronounce, or even to hear the nuances of.
Some of the pronouns brigade might find this difficult to come to terms with - as do we when they expect everybody else to remember what pronouns they've randomly claimed, which may well change from day to day. Some of them even confuse themselves and forget what pronouns they demanded yesterday.
If we've already well and truly breached the 'reasonable' barrier with pronouns, surely they can be whatever you want them to be? I presume you could tell people that your pronouns are an entire song or a Shakespeare soliloquy or something, so it will take them several minutes and a super memory every time they want to refer to you. They can hardly tell you that your non-standard pronouns are ridiculous, but theirs aren't, can they?
