惹我试试让你大姨妈倒流
[rĕ wŏ shì shì ràng nĭ dà yí mā dăo liú]
A more provocative phrase meant to intimidate or challenge someone, roughly translated to 'Mess with me and see if I don’t mess up your period.' Note that such a statement is informal, and possibly crude depending on context, used more often jokingly or among peers familiar with colloquialisms.
