I (25f) was at a party with my mom, some friends, and a couple aunts. My family has always been closer than some people find normal, and my mom is no exception. My mom is always complimenting the girls in the family to boost their confidence, and I'm always getting the most of her compliments. She was playing a card game and asked me to get her some wine, and pinched my bum as I was walking off and said "To this day I still can't believe that came from me."
A guy asked me what my relation to her was, and I said my mom, and he acted disgusted and tried to confront her. I asked him not to since while my mom had never one exactly that before, she's always complimenting my body and stuff, and I didn't think it was a big deal. Eventually he was getting angry, so I straight up told him to leave, like a command. He called me the sl word and left. AITA? It would be very upsetting to know my mom's a weirdo.
