老娘发四我比小三好
[lăo niáng fā sì wŏ bĭ xiăo sān hăo]
This name uses aggressive and vulgar language to express dissatisfaction. 'Lǎonīang' (a rough self-address meaning 'me' or 'myself') claims that she's better than the mistress ('xiǎosān', which literally means a third party in relationship). This username is typically used to show disdain for the so-called mistress.
