I LOVE THIS AU!!! It's where Sans is in the PTA, and roasts four main humans there, who are complete assholes. (Boom, I said a curse word, am I cool now?) The four main people are Linda, Helen, Diana, and Frank.
Linda: Racist cook who makes TERRIBLE lemon squares
Helen: Believes myths like vaccines give autism
Diana: Brags about her son even though she does the work for him, and thinks Frisk isn't talented at all
Frank: Sexist person who thinks girls shouldn't be allowed to do practically anything. Think before Martin Luther King Jr., but instead of racism problems, it's sexism problems.
