In modern Chinese internet slang, 海王 (Sea King) is a term for a person who 'fishes' for many romantic partners at once, maintaining a vast 'ocean' of suitors.
The term 海王 refers to the Roman god Neptune, but the Chinese translation is a descriptive title rather than a phonetic transliteration of the name.
In Chinese, the word 星 also refers to a 'celebrity' or 'star' in the entertainment industry, creating a linguistic link between the planet and fame.
