小三你妈喊你回家吃饭
[xiăo sān nĭ mā hăn nĭ huí jiā chī fàn]
'小三' (xiǎo sān) refers to a 'third party' or 'mistress' involved in extramarital affairs. Here it's humorously paired with the phrase 'your mother calling you home for dinner'. The full statement could translate as 'The mistress’s mom is calling her home for dinner'. The nickname seems to poke fun at infidelity or social misconduct using dark humor.
