小三跪求我一起捉拿小四
[xiăo sān guì qiú wŏ yī qĭ zhuō ná xiăo sì]
Referencing complex romantic relationships, this dramatic nickname means something like 'the third party begs me to catch the fourth'. 'Third' and 'fourth' here refer to those who are entangled in triangular (or quadrilateral) romantic relationships. It adds irony, as it shows the user being part of, yet also reacting against, this chaotic situation.
