大姨妈的恨
[dà yí mā de hèn]
'The Hatred Of Great Aunt' is a euphemism that refers to intense negative emotions associated with PMS or menstruation. This is used humorously in Chinese internet slang, where '大姨妈' (Da Yimā) stands for period/menstrual cycle in a lighthearted context. Here, it suggests frustration about the issues or discomfort tied to menstrual health.
