小三只不过是个收破烂的
[xiăo sān zhĭ bù guò shì gè shōu pò làn de]
This phrase, rather critical and negative, describes a third party (often derogatorily referring to an individual involved in extramarital affairs) merely as a 'garbage collector,' downgrading them as someone insignificant, unimportant or morally lacking, which can reflect cultural values toward fidelity.
