她相公他情人
[tā xiāng gōng tā qíng rén]
This nickname suggests a rather complicated love relationship. The phrase contains elements from traditional Chinese marriage, where the '相公' part originally referred to one's husband, but in modern usage, it can express a close or even romantic connection. This person might be expressing feelings involving being between lovers or trying to convey the intricate and somewhat non-traditional nature of their relationships with others.
