Person A: What are your pronouns?
Person B: I am a male
Person A: Yeah but what are your pronouns?
Person B: I AM A MALE GOD DAMMIT, COULDNT YOU TELL????????
Pronouns are a thing where you're tired of saying a name or nouns so you say things like she/he/they/it/we/me/i/you/ours etc etc. Please note that pronouns don't necessarily refer to gender identity.
NOTE: If a person corrects you nicely, they're not pronoun petty.
Person 1 - "Hey, have you seen Katie? She's been pretty off la-"
Katie - "EXCUSE ME I ONLY USE THEY/THEM PRONOUNS"
Person 1 - "Yeah whatever you pronoun petty fuck."
