你若爱我帮我停掉大姨妈
[nĭ ruò ài wŏ bāng wŏ tíng diào dà yí mā]
This phrase uses a colloquial expression in an unusual way. It means 'If you really love me, do something extraordinary or impossible for me.' 'Da yima' is a euphemism for menstruation. It reflects a desire to be relieved from monthly discomforts as a sign of true affection, combining frustration with hope.
