表子是全能型小三
[biăo zi shì quán néng xíng xiăo sān]
This nickname translates roughly to 'The mistress is a versatile third party'. It has strong negative connotations. In Chinese society, '表子' (biao zi) often refers disparagingly to a mistress who is involved in a romantic or sexual relationship with a married person. It suggests a person who intrudes into others’ relationships and possesses manipulative traits, which generally makes it an undesirable identity.
