痛经如此多娇痛得姑娘折腰
[tòng jīng rú cĭ duō jiāo tòng dé gū niáng zhé yāo]
Combines a famous phrase ('如此多娇', literally so enchanting/fascinating that it bends people double), but uses it humorously about menstrual cramps (痛经) which are causing the woman agony (痛得姑娘折腰). A lighthearted take on enduring pain from menstrual cramps that can often double one over.
