小三的葬礼我会盛装出席
[xiăo sān de zàng lĭ wŏ huì shèng zhuāng chū xí]
'I'll dress up beautifully for the mistress's funeral'. In traditional Chinese families, 小三 refers to 'the third party', usually meaning an illicit lover. The idiom expresses strong disapproval and triumph against unfaithfulness or infidelity by making fun of the situation.
