大姨妈去男人那吧
[dà yí mā qù nán rén nèi ba]
Using a euphemism for menstrual cramps humorously, this suggests that menstruation-related irritability makes the user feel so miserable that they jokingly invite 'periods' (often called '大姨妈/Auntie Period’ in Chinese) to stay away from women and go to men instead. A lighthearted way to talk about discomfort.
