小三拿走了我的垃圾
[xiăo sān ná zŏu le wŏ de lā jī]
Involves sensitive language around infidelity. It roughly translates to a third party (often used to describe someone who enters a pre-existing relationship, often romantically), taking away what was unwanted or problematic ('garbage') from someone's life, possibly indicating relief despite the complex nature of feelings attached.
