爱情庸医
[ài qíng yōng yī]
This username metaphorically refers to someone who may be skilled in matters of love but uses 'quack' methods. This term combines the theme of romance with a play on words, suggesting either the person often meddles ineptly in love affairs or that they are an emotional healer for heartbreaks. Such usernames can indicate a romantic interest or a humorous, self-deprecating attitude.
