大姨妈来了神也档不住
[dà yí mā lái le shén yĕ dàng bù zhù]
This name combines humor with a Chinese idiom and the colloquial term for menstruation (periods). In Chinese, '大姨妈' refers humorously to a person's period. The phrase '来了神也档不住' suggests that when someone's period comes, even a deity can't stop it. It reflects women's feelings during menstruation and the fact that there's no avoiding it. So it conveys the inevitability or power of nature. It’s humorous yet expresses the uncontrollable nature of certain life events.
