I asked my (23M, human) orc gf (25F, orc) to stop deadlifting my family members when she comes over for the holidays because it makes me looks small and weak, and now she and the rest of her clan keep forcing me to run laps and lift whole roasted hogs when I visit for orc holidays. AITA?
YTA. orcs like showing their affection through feats of strength. She wasn't trying to make you look weak, she was trying to show how strong your love was.
And you're also misreading their reaction. You were rude to ask her to stop, but her and her clan are very graciously addressing your concern about your lack of strength by taking on the task of training you.
