I once accidentally said to my friend, who at the time was in a relationship (tea sis, he cheated on her.), "I'm getting a divorce" instead of "I'm getting a restraining order".
Also once i asked "SO THEY'RE ALL GAY??" unironically to a teacher because i misheard something. Everyone in the class including the teacher started dying, and we still talk about this, i don't think it's that embarrassing because it was hilarious.
Talk about almost anything here
