Doing this 'joke' in a professional setting is particularly heinous.
Cis people, I need you to drag your work buddy out and explain to them that it ain't funny when they pull this shit.
I am begging cisgender people to stop using the pronoun part of their introductions in meeting to say nouns that are clearly not the pronouns they actually use.
I don't care if you have ~feelings~ about being asked pronouns. You are mocking trans people.
