你比大姨妈还烦人
[nĭ bĭ dà yí mā hái fán rén]
This name is used humorously, often in frustration. In Chinese culture, '大姨妈 (Aunt Flo)' is a euphemism for menstrual cycle. Here the user suggests that someone is more annoying than a painful or troublesome period, indicating extreme frustration with someone's nagging or bothering behavior.
