祝你和她早聚早散
[zhù nĭ hé tā zăo jù zăo sàn]
A wish with implied irony—beneath the guise of well-wishing 'good things happen fast', it hopes that two lovers find quickly what they're looking for together...and likewise, part sooner rather than later, hinting a less sincere blessing possibly stemming from bitterness or dissatisfaction.
