少年你掉了你的大姨妈
[shăo nián nĭ diào le nĭ de dà yí mā]
In a casual and perhaps teasing tone, this translates literally into 'Youth you've lost your monthly period (informally called big aunt). This unconventional and colloquial term humorously points out an emotional or hormonal disturbance normally associated with menstruation, usually aimed at males behaving irrationally.
