嘴闲就去喝大姨妈好么
[zuĭ xián jiù qù hē dà yí mā hăo me]
A somewhat crude and casual-sounding nickname that translates to 'If your mouth is free, go drink Auntie's period, why don't you?'. In Chinese slang, 'period' is sometimes jokingly referred to as '大姨妈' (Auntie Period). This name reflects a playful, impudent attitude.
